Late thread but I am seriously looking into this. Turning a normal pair of shoes into clipless is a pretty cool concept. First for people who haven't yet taken the full dive into clipless and for second people who want to create a comfortable clipless system. I plan on converting a pair of Adidas yhezys into biking shoes. I'll probably get a size smaller so it's still functional as a tight mountain biking shoe. I currently ride giro's full carbon sole shoes but looking for something comfortable and dope to wear when I'm doing my late night urban assault riding around bentonville ar. If you want to see some updates on my design let me know
