The Hellcat Pro comes equipped with a DWR synthetic upper to keep your feet warm and dry in the harshest conditions by beading up and repelling water. The 3/4 dual density vibration dampening TPU shank allows for flex when walking while maintaining rigidity when pedaling. The Stealth® C4™ rubber absorbs shock and reduces vibration and the classic Dotty™ tread gives you great traction off the bike, even in wet conditions.
