Purchased from Amazon this March. Used only once for a short period, but the size didn't fit. Therefore, the laces are already threaded(^^) Although it may vary from person to person, there's no particular smell. [Product Description] For challengers who enjoy both trails and roads. The fully remodeled CHALLENGER 7 features a slimmed-down mesh upper. The midsole, using new soft foam, increases the height from the ground and enhances cushioning. The outsole has been redesigned with the addition of a proprietary rubber, making it more suitable for both road and trail. Inspired by gravel tires, small lugs are placed closely together in the center, and large aggressive lugs are placed around the perimeter, providing excellent grip even on uneven surfaces. ■ Weight: 252g (27cm) ■ Materials: Polyester, Nylon, Thermoplastic Polyurethane, Cotton, Polyurethane, Wool ■ Reasons to choose: Combines road performance with versatile trail grip.
