I was excited to find these as I couldn't find any black Tone-Ups in stores this late in the season. In general, I LOVE the tone-ups line from Skechers and they are usually very comfortable. This particular style has a thick strap that goes across the top of the foot, and after wearing these for only a few minutes, I had blisters on the tops of both feet. I would recommend most tone-ups, but not these.
