BUY THESE
Color: Black, Size: 8
Shocked at how comfortable these shoes are. I spend a lot of time standing and moving around as an esthetician. I wore these 8-9 hours straight at work for 2 days and it was shocked at the comfort. They are just right height and cute with long pants. Super cute, I’m so glad i took a chance on these. I bought black and tan
