Wheat's Bootie Ivalos are lightweight, flexible and comfortable pre-walkers with double velcro closure that make it easy to get the perfect fit on your toddler when they go off on their first adventures. The supple chrome-free leather and suede uppers are lined and have a latex insole for extra bounce and flexibility, while the sole is made of recycled thermosplastic rubber, which offers great traction and flexibility. LWG-certified leather is leather that has been produced by tanneries that meet the Leather Working Group's standards of sustainable and responsible leather production.
