Shimano’s own rubber blend is adequately grippy and is incorporated into a pretty flexible midsole. The sole has a honeycomb pattern in the pedal zone and grippy ridges at each end for hiking.
Shimano’s cheapest flat shoes have a skate-style synthetic upper that saves over 100g compared to previous versions, with a reinforced, rubberised bumper to protect your toes. These shoes from Shimano have a skateboarding look to them.
