so Do you need a completely solid pedal to ride barefoot, without any shoes on?
there are some for beach cruisers not very good , but out there..
2 sizes , 2 widths

Ive been using them a couple years .. I also have 2 different platform MTB pedals
lyotard 460D pre spud cross pedals, campag and mavic race bike pedals , MKS 'Dutch' rubber block pedals .
the Ergon have become my favorite on the year round commuter.. I use rubber bottom boots in the winter..
