Stopped my horse's stomping within 2 days, and they've never once slipped off, even through a full show season.

Dual-Weave Mesh
Engineered in two layers. The outer weave breathes freely and blocks bites, the inner layer keeps moisture from ever getting trapped. Cooler, drier legs, even through the hottest turnout days.

"Excellent quality"
These fly boots are excellent quality and material. Iβm very impressed and I couldn't find a better deal anywhere else. Highly recommend!
"Better than super expensive ones!!!"
I got these for my 3 y/o as I wasn't sure if she would literally chew them off her front legs. She has not and so far, so good. After almost a week of use the fly boots stay on and stay upright. The velcro tabs are super convenient, I am surprised with how well these boots are holding up. At this point, I will definitely buy these again rather than the more expensive brand, when time to replace. Be sure to measure your horse's coronet. That allows the velcro tabs to be utilized fully so the boots stay on as intended.
"Must-have accessory for horse shows!"
I have two sets of these (different colors) and use them for trailering and standing at the trailer at horse shows. They have been great! Very durable and work well. I canβt review daily turnout durability, but they have been great for what I bought them for and will purchase again if needed. I will say I have big horses and these are still sized big.
"My mini donkey loves them"
I buy a pair of these every spring for my mini donkey and she wears them non stop until cold weather. They hold up great the do the job. I will buy a new pair next spring.
"Excellent value and quality"
These actually lasted me all summer. I tried these on one mare and the shooflys on another and they were very comparable in durability and quality. They did not fall down and maintained there original structure all summer. My horses are turned out during the day and stalled at night for reference. Will definitely be purchasing these again!!
"Beyond amazing!"
Beyond amazing so far. Weβve been through multiple pairs of fly boots and mask trying to find something to stay on! Going on 2 weeks and they have stayed on our 2 horses. Great quality for the price and the Velcro stays fastened well. Would definitely buy again.

Customer Reviews
Overall rating: 3.8 / 5 from 76 reviews.
These boots are a very very poor quality of a fly boot, I've order some from Amazon last year, they last me up to ordering these, those boots cost me half less as these. The support to hold these boots up are terrible, I should get a refund, terrible terrible. Very very unhappy and unsatisfied with these boots.
Jackie.
Pretty colors but this is only after almost 3 weeks. Kind of sad they arenβt staying up. My other horse has been wearing his (different brand)this entire year and they are still straight. Bummed
I like these boots! They stay up on the ankle. I would like a royal blue color so shows dirt less. Maybe also a few different sizes, so it can be tighter on the ankle so that poop doesnβt fall inside the back boots.
This is day 6, they bunch up at the bottom and fill with dirt which rubs their ankles. They need to have more structure to stay straight. The Velcro is good quality but Iβm very disappointed in this purchase especially since I ordered 3 sets.
My 22 year old quarter horse had an issue chipping his hooves in the summer from stomping and pawing at flies. With these boots he hardly stomps and his hooves have had the chance to grow out. He doesnβt mind wearing them and theyβre easy to put on/take off. Definitely recommend to anyone trying to keep their horses more comfortable during fly season.
These actually stay on my mare and they don't sag. The don't fall off. They aren't faded. These beat the more expensive fly boots hands down To people who don't understand fly boots: they aren't meant to fit tight. They will gap at the top. That's the design! Also, horses' legs aren't wider around the taller they are. Your review is unfair.
They are very nice, well made. I put them on the horses legs for the fly control and they are working great. I did spray the boot with. Skin so soft and then a few days later with citronella oil mixture to help repel the flies. They seemed to be working great.
My husband has only had the chance to use these once and then it started raining here in Oregon. But all of our team roping friends have them and that is why I bought them for my husbandβs horses for his birthday. They were great and Iβm sure weβre gonna have a whole lot more flies when the weather clears up.
Boots do help with keeping flies from horses legs and less kicks and stomping
Bad news Is the boots settling down around coronet bands and the top is wider so debris does get into them
Have to shake every leg and boot daily!
Wil be looking for a new brand one that doesnβt fall down
I have to say these are the best boots I ever got for my horses, they work retell and help slot with the flys. I do recommend them. Best Buy ever you will not be disappointed.
So after we finally received them, we tried them out, but our horse is not a fan with us even putting them on so we will have to work on that. Maybe when he gets used to us putting them on he will be ok with them and they will work
These boots are not what has been advertised as they wonβt even stay u all the way on my horse they keep crunching around his ankles. So not happy with these
Love the boots but if I would have known they were coming from china I would not have ordered them. The sales add didnβt say anything about being shipped from china.
They are not as advertised
Not only did they fall down? But they tore easily and now I have two sets that need to be thrown away due to fabric falling apart. I do not recommend them to anyone
Itβs not a one size fits all product. Theyβre too big for both our horses and the quality wasnβt the best either. The Velcro started to come apart form one fly boot and ripped the material beside it
