The Privos that I got a few years ago gave up the ghost so I was glad to see they still make them. These new ones fit the same and are just as comfortable. However, the material covering the footbed is plain rubber, which makes your foot stick to them slightly and then release on each step, and that leads to them making the same sound as cheap rubber flip-flops would make. In contrast, my old Privos had a suede-like material covering the footbed that I think was anti-microbial because they never smelled bad even after lots of walking and sweaty feet. I had even worn the old ones with a gown to formal events as I can't wear heels. The sticky rubber sound of the new ones make them unsuitable for this, but maybe applying talcum powder would help. In any case, Privo fans beware--the quality is not the same as it used to be.
