I love the Aetrex V854 walking shoes (see my review) and decided to try the runners. The brand is actually "Trex" (which kind of flipped me out when they arrived; I wondered if I'd accidentally ordered the wrong ones). I wear a 7 wide in the walkers and got the same in the runners. They have the same great feel, but even the wide is a bit narrow. Next time I'll go a half size up since I like to wear two pairs of socks when running or doing distances. Great-looking shoe (I got the blue and silver metallic) and very comfortable for just walking around doing errands, too. AND...my feet and ankles feel completely stable.
