This is American craftsmanship. The 990 continues its 30-year legacy of great performance and iconic style with the new men’s 990v4. It’s the perfect combination of cushioning and stability, wrapped up in a look that will last forever. A lightweight pigskin leather upper with mesh gives this classic men’s running shoe its inimitable look, while a combo of premium cushioning and stability deliver the feel that keeps you coming back. And we’ve made some subtle updates for this 4th generation: it’s more breathable, sports a lace keeper to keep the tongue in place, and a new streamlined “N” logo.12 mm drop: due to variances created during the development and manufacturing processes, all references to 12 mm drop are approximateBlown rubber outsoleDual density collar foamEncap PU ring with EVA (Ethyl Vinyl Acetate) coreENCAP® midsole technology provides support and maximum durabilityMedicare / HCPCS code = A5500, may be eligible for Medicare reimbursementPigskin/mesh upperWe are proud to be the only major company to make or assemble more than 4 million pairs of athletic footwear per year in the USA, which represents a limited portion of our US sales.
