Back-to-Berkeley shoes use a waterproof DryVent membrane. The mid-high design also directs rainwater flowing down the pant leg to the outside of the shoe. The shoe's styling borrows from the 80's and 90's, but structurally they are modern and comfortable instead of stiff and rigid. A great choice for day hikes and short treks, and why not for sporty everyday wear as well. - Standard fit - Upper materials include durable textile and leather reinforcements - Upper fabric and lining made from recycled bottles - Compression-molded TPU heel - Leather collar - Nickel-free metal eyelets - EVA midsole absorbs shocks - 51% of the midsole material is plant-based - Surface Ctrl rubber outsole provides good grip - 10% of the rubber outsole material comes from smallholder rubber production
