cravenmoarhead is spot on. i wear a pair of adidas adiracers. mine are about 3 years old at this point. they have a fairly stiff sole from the balls of the foot back and some flex in the front of the sole. i really like them for riding. driving on the other hand? how am i supposed to tell the difference... if i'm in a car more than an hour, anything is uncomfortable.
they're still producing the adiracers, in a fairly broad spectrum of colors if i'm not wrong. mine are a smooth leather, but i've also seen suede ones as well. i've had thoughts of picking up some red and white ones to match my bike... is that going too far?
