Instant relief from annoying arch pain approaching several weeks of running. I got them with hope because I have 105k in 2 months. My Peregrine 10s Trail are great shows too but need the extra pad and stack that Xodus provides to protect those nagging injuries. The ride so far (less than 75 miles) is reasonably responsive and surprisingly connected to the trail. Nice to walk - still have to try 20+ miles in it. Very optimistic so far. Maybe even my competition shoes.
