These are great boots. I have a slightly wider foot, but these fit great. The leather is soft and stretches. I wear an 8 to 8.5 and the size 39 fits. I sometimes get a 40, but I like the 39 better because the leather does stretch. I wear these boots to work for 8.5 hours, although I have a sit down job, I also need to be on my feet for a couple of hours and these don't hurt. The heel is easy to walk in and sturdy. I ordered another pair. I love the little extra touch of leopard print or snake print at the top. I have quite a few pairs of these boots and love the fit.Runs at least a full size small. Otherwise, great bootsFly london has not let me down, again these are lovely boots, I love the leapord print turn up and the red suede, they fit perfect and I hot at a great price.
