I'm not a runner, but I've been enjoying the shoes for casual wear, walking, and general exercise at the gym. The size 8 I ordered fits true to size for me when I wear light athletic socks. I've worn them sockless, but I find them more comfortable with the socks. They shoes are very light, and they dry extremely quickly which has come in handy when I've worn them in rainy weather on summer vacations. They wash well, too, an advantage after muddy adventures.
