If you've ever gone on a regular cruise wearing sandals but couldn't overcome their natural tendency to do multiple sprints Shimano will take your open-toe cycling into full flight with the SD5 cycling shoes. The term "shoes" is a bit of a misnomer. as the SD5 is a wind-open cycling sandal with two straps and a rubber sole fiberglass reinforced, and compatible with two-bolt studs. So whether you're heading out for a casual burrito lunch on the weekend or heading home from classes at the end of the semester for summer break you'll feel the breeze in your toes and the grip on the pedals.
