shoes should feel like a slipper light, sleek and communicative.
Some shoes use a soft rubber sole. This gives great pedal feel, but fatigues
your feet as the pedals dig in. Good shoes have a sole that
is thin but stiff. Some even use a carbon fiber plate. This
allows the sole to be extremely thin for maximum sensitivity, but also very
stiff so pedal pressure is distributed across the entire foot. The sole
should also roll up the back of the shoes and the right side of the right
foot areas that wear the most. Some use a leather pad sewn on the
right side instead of an extension of the glued rubber sole. This prevents
it from peeling away under heavy use.
