The Henri Lloyd Shadow Boot uses sport shoe technology to make it extremly comfortable and flexible whilst remaining very durable. They are designed with maximum comfort in mind and use a system called outlast which is an adaptive comfort system and regulates the temperature within the boot. It is made using Henri Lloyds TP Ocean waterproof and breathable fabric, and also uses a fast wicking fabric called dri-lex to keep the boot dry inside and wick any moisture. Water resistant uppers along with cordura make the outer of this boot extremly durable and hard wearing. The soles have been specifically designed to give you maximum grip and security whilst out on slippery deck surfaces they feature 'Sticky' rubber on both the ball and heel and have various water dispertion channels along with razor cuts. Due to it being lighter in weight than the Extreme boot it is ideal for racing conditions.
