"I love these, as I use them for myself in order to ride. I have a condition where my lower extremities are on fire, called erythromelalgia, and I ride barefoot with your ice wraps. I use them at home too. Without these, I would not have the joy of riding these majestic animals. Thank you!"

"Purchased this for my horse that has an anuaar ligament strain. Worked well to cool down the heat due to the injury. Easy to use wrap. Takes a minute to put on and less to take off."
"These are the perfect size for all of my horses. They stay cold for much longer than any other brand I’ve tried. They aren’t too bulky either."
"I was looking for a quick and easy way to ice our horses’ legs after training and these work perfectly. They stay cold for a good period of time, are durable, and super easy to put on. Much easier that handling bags of ice and other bucket-style boots!"
"These are great they freeze well and are easy to use. I use for 20 min and they are still cold when i take them off."
"They work pretty well. They don't last forever so keep extras on hand. Expensive."
"The quality of the boot was great. I loved the simple construction and cost. I use it daily for a suspensory injury and it holds the cold well. I've had it for several months and it still looks new. Thank you Schneiders!"
