“Comfortable supportive sole unit and warm, natural wool felt makes the uppers cosy, BUT they stretch a lot after a few wears. I have worn mine daily (indoors only) for about 2 months and have already had to make additional holes in the strap of one, the other is on the last hole. Perhaps a leather strap would be a better idea. The felt material has started to pill badly too. Although I did expect this, it is worse than I thought it would be. Overall, great underfoot support but I would not buy again.”
