    Mountain Horse Stella Polaris Tall Boot is rated 4.3 out of 5 by 77.
    Rated 4 out of 5 by from Wanted to love them, but couldn't. These looked perfect for our bitterly cold, snowy mountain winters. When I got them, they appeared well made, and the footbed felt true to size. The plush lining felt warm and surprisingly didn't interfere with the fit at the calf or ankle. They were, however, far too tall for me. I couldn't even bend my knee with them on. (I'm a standard short height/regular calf.) If you need a short boot height, I wouldn't bother trying them. Otherwise, I think they'd be great, even if just for for barn chores.

    Rated 5 out of 5 by from Excellent boots!! Keep your feet warm and compfy! Bought these a few weeks ago! Love them. They did send me two different sizes but they sent me a new pair right away. I was very happy with the service and they quickness to respond to the issue.

    Rated 4 out of 5 by from Very warm The boots are very warm. They have not broken in yet because we have had mild weather so they are a little stiff. Due to the thickness of the foot part, I don't really feel like I have contact with the stirrup.

    Rated 3 out of 5 by from Average I loved the boor style, but the zipper didn't even last half a season. I've been long time user of mountain horse boots, but the zippers continue to be a problem on all of them.

    Rated 5 out of 5 by from In LOVE. I am thrilled to FINALLY find a gorgeous, well made winter tall boot that actually fits my gigantic calves. I wish all of the Mountain Horse boots came in a width like these. These are true to size but I do find them a little big in the top of the ankle (I have big calves but normal sized feet and ankles...), I suspect thicker socks would fix this though. I ordered the wide calf and the measurements provided are accurate. Some people complain that the boots are too tall, I do not have a problem and I'm 5' 5". The boots are insanely comfortable from the get go and I foresee little to no break in time. The elastic panel on the side seems stiff out of the box but rest assured, it DOES stretch really well and the zipper is really sturdy. With the help of my wonderful husband, we used a shoe horn along the back (a buffer between my boot sock and the zipper) while zipping them up and had no problems at all. They zipped right up first try. I highly recommend these boots, and of course the free shipping for being a Smartperks member made them that much better.

    Rated 5 out of 5 by from Love these boots! I bought these a month or two ago for hunts in the freezing cold. They kept my feet super warm and are structured enough that they didn't rub or give me blisters like most boots with back zippers do.

    Rated 4 out of 5 by from Very warm but to stiff for my taste I am a size 8 to 8.5 on average shoe size. The size 8 boot fit my foot with room. I also have smaller than average calves; my Ariat standard calf riding boots are pretty loose on me which is why I anticipated these would also be loose. In fact, they were snug with thin socks and thin breeches underneath. When I attempted to ride in them I found them too restrictive and clumsy. In a really cold climate I can see making this trade off, but in the milder Pacific Northwest winters, in my opinion, it's just not cold enough to give up the sensitivity of my normal riding boots with thick socks. That said, they were incredibly warm and the quality is good for what they are but I couldn't see them lasting more than 2 winters of heavy use.

    Rated 4 out of 5 by from Warm & Cute boots! This was the third pair of winter riding boots that I tried and the only pair that I thought looked decent. I tried the Ice Rider's and the Ariat Bromonts and both were unattractive. These boots are sort of a riding boot meets snow bunny. They are very warm. If you live up north and want to wear relatively thick socks, then order your true shoe size. If you plan to wear thinner socks, then you might want to go down a shoe size. The only bad thing about these boots so far is that the zipper doesn't go down all of the way, soooo they are super difficult to get your foot into the first couple of times. A shoe horn will help. Each time I wear them, they are getting easier to get my foot into. Once on, they are comfy.

    Rated 5 out of 5 by from Great Winter Riding Boots! Bought these for my daughter for Christmas and she loves them. She is 5'6" and the height of the calf fits good. She has ridden in them several times already and they flex at the ankle well right out of the box. And they keep her feet warm - (we live in Michigan). Plus she loves the way they look! Haven't had them long enough to comment on quality of wear, zipper, etc.

    Rated 4 out of 5 by from Warm and Comfortable I bought these boots two winters ago. My feet got numb riding after work in the cold and dark. The boots fit pretty true to size. I normally wear an 8.5/9. The size 9s were comfortable with plenty of room for my slightly wider foot and high arch. They are nicely tapered at the ankle, more so than previous boots. The calf is true to size. The wide calf fit my 16.5 inch calves comfortably. The lining is on the calf only, not the foot portion of the boot. There is an elastic gusset down the entire side of the calf, so when my weight went up and down the boots went with them. They are exceptionally warm. Sometimes my feet got too warm while riding. I was living in New Mexico at the time (temperature slightly above freezing). They are very cute and comfortable. I wore them all the time--riding, barn chores, going to the store. Very comfortable. My one complaint about the boot is their longevity. After two half winters (bought them midway through the first winter and moved to Miami half way through the second) a hole opened up on the foot of one boot. The hole was right at the crease that forms when you bend your toe. This has been the death of almost every pair of boots I've ever had, so maybe it's just me. They were still warm, but no longer waterproof. Everything else was perfect. The sole and upper were still in perfect condition when I passed them on. I would definitely recommend these boots to anyone riding in cold weather.

    Rated 4 out of 5 by from Very warm boots! I bought these boots to keep my feet warm while I ride and they certainly do that! I went up a size in order to wear extra thick socks but they're a bit snug in the ankle so zipping is a bit of a struggle. They feel a bit clunky to ride in but I'd rather give up feel to keep warm.
    Date published: 2015-02-04
    Rated 5 out of 5 by from I really like these boots. I've worn them for about fifty hours now. I do chores and ride in them and my feet stay warm. They clean up nicely and even though my silly horse has run us along the wall a couple of times, these boots show no sign of wear. I have large calves (18") and these fit over my Irideon winter breeches and long johns. The elastic panel does stretch very nicely, but you've got to be strong enough to pull it over and then up. I added shoelaces to the zippers to make it easier to zip and to save my hands. I also have wide feet, if my feet were a regular width I could probably wear thicker socks in them, as it is I wear smartwool socks together with noble outfitters best dang boot socks in them. The shaft is the perfect height for my leg, but the first few rides they did dig into my knee pits. The first few rides they did rub my heels, not to the point of blisters, but I was glad to take them off. These boots are perfect for me, best of luck with the boot search!

    Rated 5 out of 5 by from Keeps my feet WARM! These boots are very attractive and very warm. I have had many compliments on their appearance and I can attest to their comfort.
    Date published: 2015-01-31
    Rated 5 out of 5 by from My new favorite winter boots! They look awesome, are completely waterproof and my feet do not get cold at all in these boots. I have a slim calf and normally wear an 8 1/2 or 9. I ordered an 8 and they fit perfectly.
    Date published: 2015-01-28
    Rated 5 out of 5 by from Great feel and quality. The boots are of excellent quality, I usually wear a 7.5 and the 7 was still roomy especially at the heel area. I added a half foot insert and they now fit perfectly. They are a bit too tall for my 5 ft self, but I am hoping they will relax a little with wear. I have tried 4 different brands of winter boots and these are the best yet.
    Date published: 2015-01-27
    Rated 4 out of 5 by from very pretty Although these boots are attractive they don't fit well for riding. The ankles ste stiff and the Gome up too high.

    Rated 5 out of 5 by from Gorgeous boots! These boots are gorgeous in person! I wear a 9.5 in Ariat boots and the 9 fit me perfectly. They are very warm. They are stiff, so make sure you break them in a little before wearing them to ride. I didn't and I had a hard time riding in them the first time due to the stiffness not allowing my leg to fall in it's regular place. I had lots of compliments on them at my barn!

    Rated 3 out of 5 by from Great looking & sturdy but some drawbacks I Iove the looks of this boot & tried to convince myself that they were ok. I am 5'8 and long/medium build. After trying and trying, the zipper killed my heal as I slide my foot in and they were almost impossible to zip with fleece breeches. There would be no way with bulky socks. My husband had to pull them off for me. I have exchanged them for the Mountain Horse Active Winter High Rider. Thesere much more comfortable to put on and to zip. Supposed to be warm even at 10 degrees below zero. I am much happier with this boot!

    Rated 5 out of 5 by from Great Winter Boot I bought these boots last year for a super-frigid winter, riding in sub-zero temps nearly every day, and they were awesome! I ride 4-6 days a week, and these are still in great shape half-way through the second winter. I usually wear them with a pair of Smartwool snowboarder socks, and my feet are toasty warm - if the outside temperature is 20 or higher, my feet get a bit sweaty, but never cold. Also, the shank has an elastic insert, so if I wear fleece breeches, or fleece breeches with long underwear underneath, they still zip up easily and fit well through the calf.

    Rated 5 out of 5 by from LOVE! I love these boots. It's so hard to find good boots that fit wide calves. My feet stay dry and are toasty warm.

    Rated 4 out of 5 by from So far I Love them! I bought these boots a few weeks ago so I could ride and school without my toes freezing. So far so good. I do find them a little stiff and tall, so I am hoping they will break in and be more comfortable. They are competing with my muck boots which I swear by but are not good for lessons.

    Rated 5 out of 5 by from Do you have big calves? Read this! <3 I was soooo excited to see that FINALLY an off-the-shelf tall boot would be large enough for my giantess calves. Seriously, they're over 18 inches, and I'm not hideously overweight. (Riding English is humiliating on so many levels... most brands 'wide calf' is a svelte 17. Hey Ariat, I'm talking to you!) But I digress. These came, I opened them up - and beautiful! They look every inch well-designed and fantastic quality for what they are (winter boots) and the price (not that much). Then I try them on... and I can't zip them. They say "up to 18 1/8" and my calves with breeches measure about that, maybe 18 1/4. They gap an entire 1" at the back. I am devastated. Freshly humiliated. So angry at Mountain Horse that they LIED about the upper limit. But I was in a huge hurry and put them aside to write a bad review later. Today, I had time to actually work with them... and it finally sunk in that that huge panel on the outside calf is elastic. Really strong elastic. So I pulled the outside around and...violá!! They zipped up!! Being a tall girl, they are perfectly fitted like fancy stiff dressage boots (I mostly ride dressage) so I am so very excited that they will work beautifully. Hooray!!! Just wanted to write all this so if you have wide calves and think they aren't going to fit like you thought - pull hard on that outside part and they will come right around. :-)

    Rated 3 out of 5 by from Very warm boots Purchased early November for riding on those cold Wisconsin days, boots keep my feet very warm, but bite into, and have actually cut open the back of my knees, as they are too tall for me.

    Rated 5 out of 5 by from Comfortable and warm Very comfortable boots and very easy to break in. Wonderful to wear around the barn while keeping your feet warm and dry yet comfortable to wear in the saddle with good riding support. Love them.

    Rated 4 out of 5 by from Wish there was a summer version! Just bought these so I can't give a longevity review but will say that these gorgeous boots are hitting high notes for me. Crazy warm! I live in the Pacific Northwest...the snowy, frozen version of that region...and have full confidence that these boots will keep the tootsies warm on long mountain endurance trainin rides. And then will look fashionably adorable w my skinnies when I run into town for errands. :) as always, SmartPak's service is flawless.

    Rated 3 out of 5 by from nice boots, but run very tall I bought these boots in a size 10, I'm 5'9. Can barely bend my legs in these bots they are so tall. I'm very disappointed, because otherwise I love these boots and the quality looks very good.
