WOW, these are fantastic. They feel a little odd the first few times you wear them BUT now it's all I put on my feet outside of working out/running/hiking. I've had plantar fascitis, bunion and heel spur surgery and these give me no pain, feel great to wear and are not slippery when wet. This is my favorite brand of the bunch, I have three prs of orthaheel now and want more. The blue FYI is a lovely color.
