SIZING TIPS:
We've found - by trying these on countless dancers - that these fit a half to a full size small.
So if you fit in between two sizes; say 6-6.5 it's possible you'll fit a 7 - but if you're a solid, say 6.5, you may fit a 7.5.
Because they have shoelaces across the ball of the foot, tying them to fit perfectly keeps your heel nice and snug in the back and keeps your toes from touching the end.
