Crankbrothers has partnered with Pump for Peace, the charitable arm of globally renowned pump track builders, Velosolutions, to support their mission of building pump tracks in impoverished regions of the world and encouraging more people from all walks of life to start cycling. With every purchase of these limited edition Stamp Lace shoes, Crankbrothers will be donating 20% of the proceeds to Pump for Peace, bringing the Crankbrothers Pump Track to life in a soon to be announced location.The Stamp Lace shoes feature round laces for a smooth closure and a lace pocket at the top of the tongue to store away your laces for safety and a clean aesthetic. They also have ventilated windows with perforated mesh material for breathability, a padded tongue for protection, and TPU reinforced areas for added protection and abrasion resistance. The shoes have heel dots for grip and superior heel hold, hidden eyelets for durability and a clean design, and an outsole with MC2 high-friction for grip and contact between the pedal and shoe. The Stamp tread pattern is optimized for contact surface and compatibility, with directional angled and spaced toe/heel lugs for traction while hiking. The shoes have a ramped toe for walkability and a cushioned EVA midsole for shock absorption.The sizing of these shoes uses a USA last, so please select your size based on normal UK shoe sizing. The range runs true to size, so there's no need to size up. The shoes are available in sizes 4-13, with half sizes available from 5.5-11.5.
