I didn't realize it when I ordered these but not only do you have two adjustable velcro straps on the top but the piece that goes behind your ankle is also velcro adjustable!  This ensures that you have a comfortable, secure fit no matter what type or size of foot you have.  I have high arches and these provide excellent support.

I normally am a 6.5 in dress sandals/shoes but wear size 7 in athletic shoes and size 7.5 in running shoes.  I should have compared sizes a little more but I decided to just order size 38 since most size 37s have run too small on me.  Now that I've worn the 38 a few times I think I may be in between the 37 and 38 but I'm happy with the fit of the 38.  I would rather have a little more wiggle room than have my toes at the edge.

I ordered the ice white/black color which is perfect - it is tan with black accents so it goes well with neutral colors or black.

Bottom line: superior comfort and design that is worth the investment!
