great purchase, great find. I love that I can quickly attach it to my horse and it easily conforms to the curves of his leg. I bought it to cool a swollen ankle area but it can also be used on his shins if needed. I put it on my horse 20-30 minutes at a time and the velcro straps help keep it in place (no slipping). I even used an ice boot on myself. Back problems, split shin, etc. It stays frozen for 2-3 hours and stays cool for a few more hours. Totally recommend this product to anyone looking for a simple, convenient, wallet-friendly, reusable ice boot.
