Sizing Chart for SmartPak Deluxe Relaxed Fit Fly Boots
SmartPak Deluxe Relaxed Fit Fly Boots is rated 3.8 out of 5 by 82.
Rated 3 out of 5 by from They are ok. I really wanted to like these because they do not get tight if my horse stocks up, But when they get wet they fall down. I found one around my horses ankle, the velcro did not come undone, but it was like a sock that has fallen, It was getting tight around her ankle, I am really angry about it, Not at smartpak, this is not there fault, Its the barn owner & groom who brought my horse in from the paddock & didn't care to fix it.

Rated 2 out of 5 by from Did not hold up Purchased 2 sets of these fly boots for my gelding. He got them off his hind legs within the first 2 weeks and the Velcro was ripped-he's not a horse that is hard on his clothing.. he has blankets that are upwards of 7 years old that still look pretty new except for a bit of color loss. His fronts have stayed on but aren't maintaining their shape. I did like that his legs don't get hot in them and if they had stayed on/up I would be happy to replace them each year.

Rated 5 out of 5 by from Love them!!!! I bought these for my horses, I have 3, a yearling walker(cob size), warm blood (horse size) and Belgium Cross (horse size) and they fit great and are easy to take off and on. These boots clean easy and seem to be holding up so far. Have only had them for about a month and a half now. But they seem to be made well and stay in place without any issue. I would recommend them for sure. Love how they fit and that they seem to be breathable.

Rated 5 out of 5 by from Excellent fly boots I bought these to prevent my mare stomping her feet while she is recovering from a foot injury. She has never worn fly boots before but didn’t bat an eye when I put these on. I like that they stay off the leg because I don’t have to worry about them being uncomfortable or heating her legs up. She is not allowed out of her stall but I feel like they would hold up well in turnout if needed. I also love the purple color!
Date published: 2021-06-29
Rated 5 out of 5 by from Stopped the stomping I got these last month for my horse who was stomping herself sore from all the flies. We’re in SoCal and she wears them 24/7 and in these ones she doesn’t get hot.
Date published: 2021-06-29
Rated 3 out of 5 by from Note: Quantity! Don’t overlook quantity like I did. $33 for 2… you can get 4 Shoofly boots for $45 with other sellers. So far they are fine. Lightweight as they are made from a fine mesh/tulle type material, which is nice… not convinced they will hold-up long. Time will tell.

Rated 5 out of 5 by from They fit perfectly With the amount of flies that we get in our area and how they bite on my horses legs; this product was perfect.
Date published: 2021-06-23
Rated 1 out of 5 by from Would not recommend I bought two of these, I most likely should’ve started with one pair. These do not stay on even when my horse is in the stall. They’re Velcro, so when I pick them off the floor they tend to have dirt stuck on the Velcro so overtime these will most likely become unusable. Wouldn’t recommend these. Regretting my purchase.
Date published: 2021-06-21
Rated 1 out of 5 by from Worst fly boots I have ever owned I bought 2 sets a month ago. The sticking off of 3 of them came apart after a couple days. I also noticed flies inside the boot at least 4 times. There is no sturdy loop & hook closure that it says in the description. Smart pack replaced one set that have fallen apart after one week of use. Totally disappointed in these
Date published: 2021-06-19
Rated 2 out of 5 by from Don’t stay up I was really excited about these boots, but unfortunately they fall down after a couple of days and bunch around the fetlock. They do this on both of my horses, as they each have a pair. Also, there were some loose threads on both pairs after one use, though they seem to be staying together.
Date published: 2021-06-15
Rated 2 out of 5 by from Just Ok I bought these because the ones I usually buy from a different site have been backordered since February. I ordered two pairs because, despite horses having four legs, they only come in a pack of two. One pack arrived with one horse size and one cob size - SmartPak's customer service can't be beat, and they got that corrected quickly. Sadly, the boots are just not the quality I expected them to be. My guy has legs that flies just can't resist, so he wears fly boots daily from April through October. I've already had to throw three of these away. The fit was never super great and they often slid down and off and he was often stepping on them. The velco came unstiched from the boot itself. It's too bad because I love the colors and that I can get a fly mask to match.

Rated 5 out of 5 by from Wish I could give 10 stars! Bought these for my 32 year old gelding who has a skin condition on his cannon bone. Every summer it's a battle to keep it from flaring up. Bugs swarm to it, fly boots rub! These are PERFECT. I can even adjust the top and bottom so they don't fit too tightly and cause abrasions. These are the best fly boots hands down.
Date published: 2021-06-11
Rated 2 out of 5 by from Work well, but not durable I bought these boots about 3 weeks ago. They started out great, but after intermittent use in turnout (dry lot/mowed grass area) they start to get slouchy and don't stay up. They may be good for a horse to wear while stalled, but not ideal for a horse that is mostly on turnout. They are not well suited in an area with dust/dirt or dewy grass.
Date published: 2021-06-08
Rated 5 out of 5 by from Stay put I bought these for my horse whose legs are bloody from fly bites. The work great. They stay up and stay in place even when out in the pasture. I will definitely be purchasing additional boots for my other horses and to change out and wash.
Date published: 2021-05-26
Rated 5 out of 5 by from No More Stomping! I have not used fly boots in the past, as I always thought they would slide down. However, my current mare is very sensitive with the flies and seems to non-stop stomp with her hind legs. I decided to give the SmartPak Deluxe Relaxed Fit Fly Boots a try for this season. My mare is 15.2 and is always a horse or a size large in hind boots, so I bought her size horse for her hind legs, and they fit perfectly. They stay up all day, as I only remove them when she comes inside at night. She has been wearing them every day for almost a month now, with no signs of them slipping down or slouching. She is much happier too in her paddocks.

Rated 1 out of 5 by from Stitching came apart after one use These boots were great for about 6 hours... and then the next morning I came out and the stitching on two separate pairs had come apart making them unuseable. Had to throw them away after one use.
Date published: 2021-05-25
Rated 1 out of 5 by from Fell apart at the seams I put them On my horse and the next morning the stitching had come out off the velcro. The next day the other one fell apart. They sent me a new pair and it was the same issue.
Date published: 2021-05-24
Rated 1 out of 5 by from Lasted less than a week I have an Arab who is very good at keeping things from being destroyed. His previous fly boots (different brand) lasted for 3 seasons before the spine wouldn’t stay up. These lasted less than a week. The stitching has come undone where the velcro attaches to the mesh, which caused the boot to slump and he stepped a big hole in it. Super disappointed in the quality. I also wasn’t aware these came in pairs and not all four. Had I known this previously, I wouldn’t have purchased. Now that I do know this, I absolutely would avoid as I’m not too keen on throwing ~$35 into a fire pit.

Rated 5 out of 5 by from These "socks" are better than the contoured boots I bought these about a month ago, and they are effective against flies landing on my horse's legs, and they are easy to put on. Taking them off simply requires disengaging the velcro. They are much less potentially irritating to his skin, as the tighter contoured boots do. Customer service was very helpful when I ordered these, too.
Date published: 2021-05-21
Rated 5 out of 5 by from Great product! Stan (horse) has been wearing now for about 10 days or so. So far, they have really kept their shape and they DO stay up, all day....walking or running they don't move! The only negative thing I can say is, when he comes into the barn at night and I am taking them off, it takes 2 hands (and then some) to remove the boots! LOL The Velcro REALLY keeps them in place.
Date published: 2021-05-19
Rated 4 out of 5 by from Love them! Great product as it stays in place, breathable and easy to clean! only down side is after about a month of wear and tear in the pasture velcro stitching is starting to rip off.
Date published: 2021-05-15
Rated 4 out of 5 by from I love the concept of the mesh material...cooler. My only complaint is there is not much room for size adjustment at the top. My mare has these on 24/7 and I believe an added benefit may be that ticks cannot crawl up her legs....yes, I would recommend these.
Date published: 2021-05-13
Rated 4 out of 5 by from Great product Works well. Stays up. I bought the purple and orange pair so they would be easy to find in the pasture. So far so good. My guys have not gotten them off and they have stayed up. The only con I find is the top band I would like to be a little tighter. One of my guys has skinny legs. There is a space where maybe the flies can get through.
Date published: 2021-05-05
Rated 5 out of 5 by from LOVE! These are the best fly boots! They stay up, don't cause rubs and are soft enough to leave on over night. I bought both of my mares a full set.

Rated 4 out of 5 by from Saving my pony's legs My qtr/welsh gets dermatitis from bug bites and our barn is right next to a creek so the mosquitoes are horrible. But he is hard to fit with most horse clothes and gets overheated easily. I have tried several brands/styles of fly boots and so far these are the only ones that both fit and and let his legs breathe. Been using them for three weeks now - the skin on his legs is much improved and the mesh is holding up quite well. And bonus - great color options! I will be ordering another set. WHY NOT 5 STARS? The velcro stitching is already coming apart. I will have to repair/reinforce it but the rest of the boot is worth it for saving my pony's legs.

Rated 5 out of 5 by from Finally! The best fly boot out there! I bought these fly boots a few weeks ago when I just by chance saw a few last pairs available on Smartpak. I have been searching all season for unfitted ("relaxed fit") fly boots that won't constrict my QH's legs, especially his hind fetlocks which are dropped, making fitting there a challenge. Fortunately I was able to get a pair of these before they sold out for the season and they are as wonderful as I had hoped! I have tried a half dozen different pairs of fly boots, Smartpak brand and not, in a variety of materials, and none come close to these. The "relaxed fit" is great, and they stay up when in turnout or grazing as well as "breathe" on really hot days. I use them even in my boy's stall to keep flies off his legs, especially on a healing fetlock + pastern cut that attract flies. I only wish Smartpak had more in stock so that I could order 2 more pairs - an extra pair to make a complete set of 4 (it is too bad they only come in a pair) and an extra pair when the others are washing! Thank you, Smartpak, and please bring these back - even going into fall and winter, they would be very useful!

Rated 4 out of 5 by from Love these! Great design. I bought these for a 16HH Appendix QH. I bought horse size. I love them! It is very hot and humid here (MD), and my horse sweats more than most. These are very airy. He wears them 24/7 and lives outside only. It is true that they are not durable. However, they are more durable than you may think. He can wear them 4-5 days straight with no issues. Then, one or two of them will crumple down around his ankle. At that point, I remove them (and switch out his fly boots for the Cashel ones - which are awesome) and wash them. I hand them to dry and put clamps all down the length of them so that they dry flat and straight. This seems to fix the "crumpling". These boots are much better than the models that come with boning inside. All of those also crumple, and then the boning (plastic strip) pokes out. You cannot use my drying technique to fix that. At first I didn't like the fact that these boots don't cover the pastern. However, it has not been a problem at all. The flies stay away. Without boots my horse gets eaten alive and stomps his feet apart. These are great. Also highly recommend the Cashel fly boots for a more fitted boot. I love them both an alternate them. These ones are better when it's super humid.

Rated 2 out of 5 by from Do Not Hold Up With Turnout these fly boots are nice however they do not hold up well if your horse receives daily turnout. Bought these early May and they are already falling apart. Horse is not that rough with turnout either.

Rated 5 out of 5 by from Best fly boots ever great price I needed one pair for one horses back legs that did not constrict her movement-awesome! My other horse wears magnets boots fit great with them on great boots! I will be ordering more! Easy to wash as well. Fits true to size.
