Those lucky enough to have a narrow foot should be able to enjoy these. There is a strange plastic thing inside the upper lace loop. This is one of those simple devices that is extremely configurable. My bad! Super bike stand ?? The 2nd pair broke after about 8 wears. Man hört also Umgebungsgeräusche. About 25, 30 minutes later, it was all done. I hope they are going to be very durable. I like getting that previously broken-in feel when I put on a new pair of stilettos.
