The fit is generally good, but if you want to wear winter socks I would recommend going half a size up. I bought these as a backup shoe but actually wore them a lot. Good comfort.
Pros
BUILT FOR COMFORT: Our soft interior design, two-tone exterior and memory foam insoles offer flexibility, comfort, impact/slip resistance and traction with every step, making them ideal for any activity, climate or environment. Unlike many chukka boots, we've added a heel pod to not only eliminate wrinkles when stepping in, but also allow for a tension-free on and off motion.
