One of the best flat pedals that are equipped with safe traction moulds (instead of traction pins) are Race Face "Ride". Regarding the metal traction pin pedals, any regular shoes will do, as the pins simply bite into the shoe soles for the ride. Not that it is perfect. Therefore, many of us invested in Adidas FiveTen Freerider Pro shoes, soles of which are ideal for traction-pin-pedals, and the shoes are so strong your toes will be properly protected against any impact.
