Over ten years ago, we released the very first Quarry work boot. Since then, it has become a staple for workers around the country. And now, for the first time, we've brought manufacturing of the Quarry, using imported parts, to our Portland, Oregon, factory, at the same time making major improvements to its comfort and durability. GORE-TEX (GTX) 100% waterproof and breathable, GORE-TEX liners ensure that no water gets in, while allowing sweat and moisture to get out. Triple Stitched Hyper-strong thread is used to triple stitch our toughest boots. Alloy Toe (AT) Our alloy toe meets or exceeds ASTM F2413-11 I/75 C/75 EH standards. Electrical Hazard (EH) Protection Electrical hazard (EH) footwear is manufactured with non-conductive electrical shock resistant soles and heels. Quarry Midsole Upgraded the midsole to a single, solid piece for increased longevity Vibram® Quarry Outsole This exclusive outsole features a 90º heel, an oil- and slip- resistant rubber compound, and a non-linear lug pattern for superior traction and debris release. Stitchdown Construction Handcrafted to provide a wider platform, our legendary stitchdown construction offers increased stability underfoot. Many of our stitchdown boots can be recrafted. How It Fits The 610 is our most universal last and can be worn by all foot shapes and sizes. It provides a snug fit through the heel while allowing ample toe room for most versatile fit. This allows more support and side-to-side movement. Recraftable Extend the life of your boot with our recrafting services. This boot is eligible for a number of paid services, including part replacement, leather care and restitching.
