When I received the shoes they were a little tight but felt comfortable. I left them for better weather so only wore them a couple of times. The fifth time I put them on I could barely get through my crotch and by the time I was done I had deep burst blisters on both heels. The fabric on the heels had frayed, exposing the hard plastic that had torn my heels. I never write product reviews but the quality of this product was terrible and it took my heels three weeks to get better.
