I bought these because I was replacing my gravel bike pedals with mountain bike pedals. The first time I actually used them was when I rode 120 miles of gravel. I didn't even notice them on the street. I usually wear road bike shoes and spikes. It's fantastic that I didn't notice anything about it. The fit was very good and I had no abnormal scuffs or blisters. I was planning to buy a pair of MTB Fizik but they were a much cheaper option and they worked fantastic.
