They fit very well and are comfortable. With a strap and wire, they are easy to tighten and loosen when needed. Synthetic material feels like leather. I used them on a Peloton with Delta clips and used the screws that came with the clips to attach them to the shoe rather than the screws that came with the shoes. They've performed reasonably well in the peloton, so they're worth a try. My feet were comfortable during the ride.
