- Color: Gray - Sole: White sole - Style: Slip-on Purchased at a department store. The staff at Staccato are all very passionate about their products and provide detailed explanations. The heel is leather. I bought these because they have a thick sole and are expected to make your legs look longer, and the staff recommended them for travel. I used them on a two-night trip, so they are in very good condition. The strap on the left instep is originally loose, but I was able to wear them without any slippage when taking them off and putting them on. Please check the last photo. No box.
