Our proprietary 3D-formed Ballistic Fabric Material provides puncture resistance from scrap metal, screws, nails and other hazards. The proprietary 3D shaping of the ballistic fabric provides expanded coverage of the arch and heel area from punctures – and the puncture resistant material extends. The insole features our famous Dr. Scholl’s ergonomic contour footbed and arch support, proven to provide all-day comfort. The dual layer insole features a top layer of our Gel-Foam which provides 2x more energy return vs standard foams.
