One of our rescue horses, age 25, has developed stifle problems. These horse boots help to steady his walk and enable him to keep up with the herd. We have been keeping them on for two days and the night in between then taking them off for the next night before putting them on again the following morning. We think that the wraps need to air out. They are relatively easy to put on and take off although there is the usual problem with velcro sticking to everything when you are trying to remove it. However, the velcro keeps the wraps snug and in place. We couldn't be more pleased with the product.
