Love them! I was a little nervous about a) the sizing (usual size, or size up?) and b) the ankle height (will they rub and be uncomfortable?). So, in the end I took a punt and went with my regular EU41 size, checking the size chart of course, and they are good for me. I probably could have gone bigger, but these still work with or without socks, with plenty of toe splay room. They stay on nicely. I do have quite a high instep on one of my feet and these did feel a little tight to start with as they come quite far up the top of the foot. However, they are fitting better after lots of use now. With regards to the ankle height - yes, they do come up quite high. I think this is because they can be for ladies or gents. The first few times I wore with socks just in case they rubbed and I didn't notice anything. So then I wore them without and the first time I thought maybe they were rubbing, but actually I haven't any blisters or rub marks so they appear to be fine; and I do have chunky low ankles. The material is quite soft, so that does help. I would've liked these in black (I'm a black shoe kind of gal!), but the blue is lovely and deep. The only thing is, with the nature of the material, they do sort of look creased on the top with use. However, doesn't bother me. On the whole, delighted with them - wanted a slip-on-wear-anywhere type of shoe, and this is it for me... though I haven't worn them in the rain, so not sure how they will get on if I get caught out in a shower!
