Sandals AGATHA RUIZ DE LA PRADA 222955-A M Blanco Y Corazones Rider R Next in-shoeals are built just like the regular pairs, but there are a couple of key differences. The first is the marbled pattern across the forefoot strap, and the second is the QR code that takes you to the brand’s site. Everything else is unchanged, though, with a moulded footbed providing all-day comfort and a detachable heel strap allowing for it to be turned into a slip-on.
