If you are a hardcore driver you will love these parts! The pedal feel increases by leaps and bounds. Once they're on, the feeling is even better as they become more flexible! It's like you have no shoes at all. For sizing reference, I usually wear 11.5-12 and 10.5 on Converse All Stars. I chose size 46 for them and they are perfect. *Note: If you have a very wide foot you will not like these shoes as they are narrow. For reference, I wear D-width boots.
