Slip-on vs.Lace -up
I tried both this and the newer lace-up version of this super lightweight shoe, but sent this one back. These easily run a half size small, and are quite difficult to get on. I didn't feel like the heel tab adjust was of any use to me. They are comfortable enough without a sock, however the laced version runs true to size and allows room for that option. The laced version also has a roomier toebox and more width across the ball of the foot. If you have narrow feet and/or low-profile toes you might like the slip-on model better. Both are ridiculously light and compact, and I plan to take them backpacking for river crossing and camp shoes as well as general hiking and running.
