Product Details The Waterproof Boulder Boot has long been our most requested shoe, and we’re confident that they’ll be worth the wait. Speaking of weight, this boot still maintains the lightweight frame you’ve come to know and love from Lems — even though we’ve added a unique waterproof membrane, these puppies will still hit the scale at a featherlight 12.9oz. Specs Waterproofing: 100% - breathable waterproof membrane Tongue Construction: gusseted Last: Lems WIDE Natural-Shape™ Last Upper: Full-grain oiled leather Lining: Full-grain leather + moisture wicking Outsole: 9.0mm LemsRubber™ (air-injection rubber) Insole: 3.5mm removable PU insole Stack Height: 10.0mm (not including 3.5mm insole) Drop: 0.0mm (Zero-Drop) Weight: 12.9oz (Women's size 9.5) I got these as a gift and sadly never have worn them. These do run a little small. I normally wear an 8.5 and these fit perfect. Brand new without the box.
