My old girl has incredibly sensitive skin and gets mud fever really easily. These have been the only thing that have actually prevented it. I have 6 full sets just to make sure I always have a clean, dry set. Though they dry very quickly.
Ive been using them all this winter and she is out every day. They haven’t caused any irritation which I have found with other mud boots when used a lot. You do have to make sure they are properly fitted though.
Highly recommended.
