I picked up a pair of these last month when I'd gone out of town and left my workout shoes at home.  These were on sale at the store I went to.  Normally, I'm a solid 6 1/2-- if anything, I tend to go down to a 6.  But, I had to buy these in a 7 to fit comfortably.

I didn't expect to like them as much as I did!  I actually bought 2 pairs through Amazone-- 1 in pink and 1 in purple.  I've received many compliments on the pink (I've worn the purple indoors at home only).

I am using these shoes for high intensity interval training-- lots of jumping, quick floor movements.  They are very stable, provide a good amount of support, and cushion my feet very well.
