...one - not so good - reason....waiting to collect enough info to decide what kind & hoping a single style can allow you to use the same type shoes for all the bikes you ride & allows a type of shoe you can walk in when you are out on a ride. In my case, I'm not into the 'costume' aspect of road or MTB or urban MTB or hipster riding...just looking for good power circles, grip/safety & a bit of practicality!
