I don’t know that I would say it could completely replace an actual ice boot, but probably about as cold as just cold hosing. Would I use it as my only icing option for an acute injury? Probably not. Would I use it on my horse’s legs after a moderate jump school at a horse show? Yes!
Edit: if you do get them, make sure to keep the bag they come in. They’re supposed to not completely dry out between uses in order to prolong the life of the product….I did not follow those directions and regularly hung my towel to dry 🫣 while I haven’t noticed any degradation of the product, I do prefer to try and follow directions lol
