I wear a US size 11 and these shoes fits great. Finding the correct size via the internet is troublesome. I use them only for competition so I can't rate about their durability. Using them on rubber (competition) mats and wooden floors they hold my feet snug, fairly lightweight, and allow me to move laterally.
Their color pattern is catchy, although they could do away with the silver and just have them white/blue (that's the bling on the Cons).
I believe in spending good money on good shoes and I feel I have spent wisely.
Now if I can click my heels 3X to get into position for the ball, I'll be thrilled
