Just arrived in the mail yesterday, fit like a glove and super comfy without any help.
I ordered my usual size 8, and these have no room to spare.  I won't be able to wear a thick sock like I usually do, but with a pair of trouser socks or leotards and I'm good to go.
Thinking about ordering a similar style of Clarks in black for the spring : )
Sometimes you just can't go wrong with this brand.
