The comfortable Ultra 50 running shoe for men was developed with long trail runs in mind. It is just at home on technical terrain as it is on soft surfaces. Run without limits – no matter where, no matter how far. On demanding alpine trails, your feet need a shoe that offers all-round protection and a sure grip but not weighed down by anything unneeded. For distances of 40k and longer, you must have good cushioning and a comfortable fit to guarantee top performance all the way to the finish line.
