Women's Aerosoles Bia Flats The Bia, by Aerosoles Shoes, is our ballet flat with lovely new details—a longer round toe that’s sophisticated, and new iconic ornamentation—a buckle and bow interlocking link effect, which sparks up a new tension into the conversation. Stitch & Turn construction means Bia requires no break-in time to be completely comfortable. Bia dazzles and inspires with all of the fascinating facets of womankind: we’re elegant and tough, stellar yet understated, leading and ruling, but always changing the game.
