Have (mostly) 43er and a high instep: the Roc Legend Mid GT fits very well in the UKGröße 9.5, at first it was rather just get dressed. The socks stay dry (hike in light steady rain / biking in the rain) and I do not sweat it too. The sole is a bit hard and thin, but that actually fits. Colorful, but well matched colors and made in China. I wear these shoes often like.
