Re: walking -- If I often add a "stop" on long rides - a bagel shop, a bike shop, an historical site, etc. - I'd like to be able to walk comfortably and safely in those places. I sometimes bring rubber slippers, but they're awkward carry on a bike.
I'm more of a touring cyclist, I guess, rather than a racing cyclist. I just haven't started shopping for the right pedals and shoes yet.
