I thought I wouldn't have any troubled with recessed cleat shoes, but these have been so annoying off the bike. The shoes are silent when I'm inside on tile or marble type floors, but on slightly rougher surfaces like concrete sidewalks they scrape and grind. I bought these shoes specifically for every day use, which means as much time on the bike as off. I'm about ready to throw in the towel and just put platforms back on my bike. Does anyone have any suggestions for fixing this problem?
