The paw protector was advised by my dog's physio to help with a deformed paw, he was walking on bone. The product has helped him rebuild his padding so that there a times when he can go without.
The only down side is the neoprene cover, this caused him the lose his balance in the rain, and frightened both myself and him. So now I cut this off.
My dog is so happy to wear the protector that he aids me when fitting it.
