The Pearl Izumi Synchro Fuel II Trail Runners are a great, lightweight but full support shoe. After wearing them around the neighborhood for a bit, I put only five miles on the trail in them before fast packing 26 miles round trip on Pikes Peak. <br /><br />Starting from 6,500', topping out at 14,110' and back, 26 miles is a long day to break in a pair of shoes. These Pearl Izumi shoes performed flawlessly.<br /><br />Pearl Izumi Synchro Fuel Trail II: http://goo.gl/lCRPg
