They just arrived. I couldn't get them on. I took my socks off and tried again - they are very tight to get into. The size seems right for my foot but the opening is tight to get into and they are tight over the top of the foot. I am going to leave them on for a bit before I decide what to do.

Update - I decided to return them - I think the arch of my foot is too high for them. They are really well made - just uncomfortably tight across the top of my foot.
