Thanks for your ladies' help. I live no where near a major CL retailer so don't have the opportunity to try them on and I can't find the Mrs. Boxe anywhere so I am trying out eBay with a reputable seller. Now my question is.... I wear a 7 in flats, but size down to a 6.5 in heels to prevent my foot from slipping. I know that the Mrs. Boxe will run small, so Should I size up to a 7 or 7.5? Thanks.
