I thought it might help to provide some insight for those who don’t bike at all. All of the entries have been excellent!
In my opinion, the parts of the actual cycling shoe (I’m ignoring the shoe/ cleat interface – that’s a whole other animal) that could still use design improvements include (along with currently available products):
-
Closure system – need to be secure, but not constricting and adjustable while riding the bike.

Speed and ease of getting the shoe on and off

Of course, there are many different types of riders who are interested in different designs.
- Recreational / Lifestyle wear – want to look cool wearing cycling shoes all day and be able to walk easily in the shoes
- Road racer: want light, stiff, secure, efficient shoes
- Triathletes: Want light, secure shoes that can be put on and off very quickly and easily
- Time trialists: same as road racers, but with a super smooth, aerodynamic covering
- Mountain bikers: Rugged, with tread. Sometimes need to run in the shoes to get over things.
