Product Description: Trimmed down for performance and still as supportive and cushioned as ever, the Timp 4 has been retooled to do it all from daily miles to your favorite trail races. A biomechanically improved outsole design is combined with a new upper and lacing design to provide a better locked-in feel mile after mile. Finished off with a resilient Quantic with InnerFlex midsole and a grippy MaxTrac rubber underfoot, the Timp 4 is locked, loaded and ready to hit the backroads.
