    Rated 5 out of 5 by from Great quality I have been using these fly boots for about a month on a horse who is turned out all day and has to maneuver a rough steep trail going to & from the pasture. The boots show no sign of wear, are easy to put on, the Velcro is very strong and they were offered at a fantastic price!

    Rated 5 out of 5 by from boots keep flies away. Living in a hot area of California flies are a problem. These boots keep my big guy from stomping. These are a replacement for the set he is wearing. The boots usually last at least one summer. The velcro keeps them in place although with my arthritis sometimes the velcro is hard to grip & pull off.

    Rated 2 out of 5 by from They fall down I have a 17.2 hand warmblood and bought Horse size. They fall down every day, no matter how tight we make them. I've only had them for a few weeks.

    Rated 4 out of 5 by from Nice Boot, Very Large! Ordered "Horse" size and they are good for our very big WalkerXQH cross but still a little big. I have the "Cob" size for my 14.3 QH and they fit very well. One of the horses ripped off a piece of the velcro otherwise they seem to be good quality. They do tend to slide down and thus need to be checked daily.

    Rated 5 out of 5 by from Love these!! I bought these 3 months ago and they are awesome. They stay up on the horses leg, and I have yet to have one fall off in the pasture and my horse has completely stopped stomping her feet from flys. Definitely worth their weight in gold.
    Date published: 2017-09-07
    Rated 4 out of 5 by from Worked great, stayed up, mostly! These boots were too large for my average sized horse, so would definitely get a Cob size next time. They were light weight, and even being large, they mostly stayed in place. My mare sure liked them though, and they absolutely help the horse be more comfortable not having flied on her lower leg. I will get another pair for next season, there is still some life left, but they showed wear and tear after several weeks and a lot of rainy days.

    Rated 3 out of 5 by from Slouchy These are pretty well made but I can't get them to stay up. They slouch quite a bit, especially the back ones. I put them pretty tight but the back ones slouched so low that he kept trying to kick them off. Had to take them off to stop his kicking. The front ones slouch to about six inches below his knee. At least it protects them a little there.

    Rated 3 out of 5 by from Okay These boots are super soft and well made. However they fit really large. They slide down on my gelding and he has already pulled off Velcro.

    Rated 4 out of 5 by from Still looking for the perfect fly boots The horse size fits my 16 hand tb if I really tighten them. She mainly wears them in her stall and they do slip a bit but not dangerously so. They are breathable and cool but I expect they would get wet and stay that way. They are soft and she's gotten no rubs.

    Rated 5 out of 5 by from Very high quality flyboots I bought a month ago. These are holding up nicely. Wash beautifully. The Velcro closures are super heavy duty and the fabric is soft and breathable. For the price I was pleasantly surprised.

    Rated 3 out of 5 by from Broke down quickly I bought two pair so that I could keep them clean and in good condition - anything worn 24-7 takes a beating, right?! Things went well for two weeks, while I was there to switch them out, shift & straighten. I went on vacation for one week & came back to soggy, hanging, worn out (the bottom was ripped) boots. Without them being fixed every day, they slipped down, got wet and heavy, and just didn't last. I was very disapponted. The extra softness and thickness that sold me, turned out to be negatives. The dirt got very trapped in the layers too which made it very difficult to wash. Back to the Kensingtons that lasted me two fly seasons!

    Rated 4 out of 5 by from Keeps the Flys away My thin skinned chestnut appreciates these! They stay up and keep the fly's away. He doesn't do much when he's turned out (i.e. run) but he does roll and they stay up with no problem. They're fraying a little where the velcro is, but appears to be only cosmetic

    Date published: 2017-08-09
    Rated 1 out of 5 by from Fly Boots After one day, my horse came in with two boots ripped. The Velcro came off very easily, so these need more stitching. Disappointed in the longevity. I have found Cashel fly wraps work better, and I have some that are three years old.
    Date published: 2017-08-09
    Rated 1 out of 5 by from Disappointed Got these for my mare who was being eaten alive by flies. She is about 15.3hh and stocky. The boots had to have more Velcro added as they were to big around and they kept slipping down. There is virtually no structural support so the wilt. The height of the boots were great.

    Rated 1 out of 5 by from Throughly unimpressed I bought these for my Thoroughbred mare, I sized them down after reading the reviews. After making sure they were snug and seemed to be fitting properly in the barn, I turned her out. Within 5 minutes of light trotting around, they had fallen so far down her legs that they were completely bunched at her coronet bands. I know for sure had I left them on, they would have rubbed her raw. Now I can't even return them because they are used for that five minutes.

    Rated 4 out of 5 by from Does deter flies...but! Does help with flies however they do slip a bit especially if they are looser and can turn. However I feel that you really have to put them on tighter than I'd prefer for a full day. I get worried about my horses legs getting too hot so I do check this.
    Date published: 2017-08-07
    Rated 3 out of 5 by from Well made. Theses fly boots are well made. However they slouched down after a day of wearing. Readjusted them with difference. I was disappointed as this horse has bad hooves and I was trying to cut out some of the stomping.
    Date published: 2017-08-02
    Rated 5 out of 5 by from No slouch! I bought these a few weeks ago and have used the Cob size on my 15hh Arabian, and 16.2hh Appendix with great results! No more stomping! After reading reviews, I decided to get the smaller size and I have no complaints regarding size. These boots spin around, but they tend not to slouch as much as other boots. The Appendix likes to abuse his stuff, and so far, these boots have remained unscathed.. which is a miracle, really. The velcro is SUPER strong, and the boots themselves are ergonomically designed so they fit snuggly under fetlocks. Definitely glad I bought these!!

    Rated 1 out of 5 by from AWFUL!!! I bought these boots to help keep flus from biting my horses legs. When I opened the package I notice they were not at all stiff and I felt may not ventilate on hot days; but I'll try them. Wished I would have just sent them back. Four days later. I am currently cold hosing my horses leg because the boot slid down and cut off his circulation. Leg is extremely swollen and he can't put weight on it. The vet said this is his second case this year from the same boot. Absolutely awful!! My other

    Rated 5 out of 5 by from Wonderfully hard to take off! These are hard to get off therefore they stay on! I am very impressed! Will buy more! They wash wrll, too!
    Date published: 2017-07-27
    Rated 3 out of 5 by from Does the job Bought these to help with flys and the first day they slid down. They work once they are broken in. Good quality, tough Velcro so horse buddies cannot get them off, and they don't seem to heat the leg. Make sure you have proper know-how on how to operate boots as to not put them on the wrong leg
    Date published: 2017-07-26
    Rated 1 out of 5 by from Don't stay in place Bought the Horse size for my 17.1h Trakhenner. I worry they will cause a bow if they get a tight spot as they end up scrunched and twisted halfway down his leg... he's 19 and in a paddock but not overly active, and yes the Velcro tabs are adjusted snugly when they are first put on. Already wearing holes in them after 2 weeks of use...

    Rated 2 out of 5 by from Too big and don't stay up Although these boots look like they are constructed well enough to get through at least one fly season, they simply would not stay upright on my horse's legs. Particularly his hind legs. They would be wrapped around his fetlocks in a matter of hours no matter how tightly I secured the velcro straps. They seemed big so I washed them and dried them in the sun hoping they would shrink in size a bit, but that still didn't help matters.
    Date published: 2017-07-25
    Rated 4 out of 5 by from DURABLE I have had a pair of these for SEVERAL years and love them. The only thing is I took out the plastic "spine" that is supposed to keep them from falling down because it was chafing my horse in the back. Since I did that I've had NO problem and and now ordering 2 more pair-- one for my young horse and another for spare since they are on sale!!! Have tried all others-- these wash well, wear well, and the giant velcro square keeps them on all day...

    Rated 5 out of 5 by from Worked great! I bought a set of these in cob size for my mare who stomps constantly, and actually used the hinds on the front legs of my bigger gelding and so far they're staying on, and not getting destroyed, and definitely help with the stomping.
    Date published: 2017-07-22
    Rated 4 out of 5 by from Great product, but for sure runs large These fly boots are great, they work well and they stay up, I've kept them on my mares for days and while they rotate a bit they don't fall down or rub which would cause me worry. However they are large. After reading reviews I got the cob size and they fit with room on both my 15.2hh TB and my 16.1 holsteiner/ TB mares
    Date published: 2017-07-21
    Rated 1 out of 5 by from Do not waste your money on these! I bought two pairs of these to try on my two TBs. Both are average size, and normally wear M sized boots. I got cob sizes for them. I was hoping they would help with stomping at flies all day. These are the WORST product I have ever purchased from Smartpak. They are a huge disappointment and I wish I could return them and get my money back. First of all, they are huge even in Cob. Second, they don't stay up at all, no matter what you do. Third and probably worst of all, when they do fall down, they rub my horses legs raw in spots. My older gelding has a huge, bloody welt from his rear boot and I found my younger one stepping on his because even though I put them as tight as they go, they don't stay up at all. DO NOT BUY THESE!
