The FlyBlock Boots

Why People Love It!

Built to Block Bites

Mesh creates a physical barrier flies simply can't get through. In a research, leggings cut stomping by up to 65%*. So your horse can finally stand still, eat in peace, and stop fighting bites all day.

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.

One Size, Every Horse

No sizing chart, no measuring, no guessing. FlyBlock's Micro-Grip closure adjusts to fit snugly on everything from compact ponies to full-size draft horses. The same boot, on every horse in the barn.

Micro-Grip Fastening System

Interlocking at a microscopic fiber level, not basic velcro. Paired with sewn-in plastic stays that hold their shape, FlyBlock stays secure at the walk, the trot, and everywhere in between.

Wear It Anywhere

Out in the pasture, back in the barn, or halfway through a ride. FlyBlock keeps working the whole day through.

Field & Turnout

"Excellent quality"

These fly boots are excellent quality and material. I’m 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 can’t 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. We’ve 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 photo review of The FlyBlock Boots

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 aren’t staying up. My other horse has been wearing his (different brand)this entire year and they are still straight. Bummed

Customer photo review of The FlyBlock Boots

Love your fly boots! They are easy to put on and so easy to clean! They stay on and do their job. Love the colors as well.

The FlyBlock Boots

Customer photo review of The FlyBlock Boots

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 doesn’t fall inside the back boots.

The FlyBlock Boots

Customer photo review of The FlyBlock 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 I’m very disappointed in this purchase especially since I ordered 3 sets.

Customer photo review of The FlyBlock Boots

A bit expensive but if they hold up, then worth it. We shall see,

The FlyBlock Boots

Customer photo review of The FlyBlock Boots

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 doesn’t mind wearing them and they’re easy to put on/take off. Definitely recommend to anyone trying to keep their horses more comfortable during fly season.

The FlyBlock Boots

Customer photo review of The FlyBlock Boots

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.

Customer photo review of The FlyBlock Boots

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.

The FlyBlock Boots

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 husbandβ€˜s horses for his birthday. They were great and I’m sure we’re gonna have a whole lot more flies when the weather clears up.

The FlyBlock Boots

This is my favorite style of boot. Great price.

The FlyBlock Boots

Best fly boots I have ever bought. Still think they are a bit expensive for the simple design, but they work

The FlyBlock Boots

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 doesn’t fall down

The FlyBlock Boots

Great product for the money

The FlyBlock Boots

Great value. These are my favorite style of fly boot.

The FlyBlock Boots

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.

The FlyBlock Boots

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

The FlyBlock Boots

Product was not like advertised they won’t even stay up on my horses legs they keep falling down around his ankles. Would not recommend this product

The FlyBlock Boots

These boots are not what has been advertised as they won’t even stay u all the way on my horse they keep crunching around his ankles. So not happy with these

The FlyBlock Boots

Like the quality but they are to long on my horses legs

The FlyBlock Boots

Boots are to long for my 2 horses legs

The FlyBlock Boots

Love the boots but if I would have known they were coming from china I would not have ordered them. The sales add didn’t say anything about being shipped from china.

The FlyBlock Boots

Love these. They have made a huge difference for my horses. They can stand comfortably without constant stomping

The FlyBlock Boots

They are WAAAY to big for even my biggest horse… fell right off 😒

The FlyBlock Boots

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

The FlyBlock Boots

These are fantastic, they help my horses slot, I would recommend fir these are the best ivevery bought to protect my horse fit Butherus. Thsnkbyoun

The FlyBlock Boots

It’s not a one size fits all product. They’re too big for both our horses and the quality wasn’t the best either. The Velcro started to come apart form one fly boot and ripped the material beside it

The FlyBlock Boots

I think better quality material would help to not tear so easily and add extra velcro for a little snugger fit.

The FlyBlock Boots

Absolutely waaaaaay to big!!! Fell right off of my biggest horse.

The FlyBlock Boots

Scrunch down after a week. Sent pictures. Told to tighten belt. No belt. Totally ignored Worst customer service ever.
