Key features include a TPEE Air Mesh Upper for ventilation and durability, a perforated and padded tongue for comfort and breathability, and raised sidewalls for security and flexibility. The shoes are equipped with TPU toecaps for toe protection, heel pull tabs for easy on-and-off, and a traditional lacing system for a secure midfoot fit. The DNA Loft v3 Midsole provides super-soft cushioning infused with nitrogen for a lightweight and durable feel, helping to reduce impact on joints. The TrailTack Green Rubber Outsole ensures optimal grip and traction, even on wet surfaces, and is made with 25% recycled materials.

The lug depth is 4mm, with a heel height of 38mm and a forefoot height of 32mm, resulting in a 6mm drop. The shoes weigh 301g. The TPEE air mesh upper actively wicks away sweat and moisture, creating a drier, healthier foot environment and resists snagging on the trail. The padded and perforated tongue enhances comfort, while raised sidewalls add security and flexibility. TPU toecaps protect the forefoot, and heel pull tabs assist with shoe entry. The lacing system ensures a locked-in feel. The DNA Loft v3 midsole is soft, comfortable, and conforms to the underfoot shape, providing excellent support and cushioning to attenuate shock and minimize discomfort. The TrailTack Green Rubber outsole and multi-directional lugs deliver outstanding traction on various terrains, including wet surfaces. Its durable, non-skid rubber provides optimal grip for technical trails, and the wider base improves stability for smoother transitions. Flex grooves increase flexibility for better grip and traction. The mesh upper is breathable, protective, and adds flexibility for a smooth, seamless feel, complemented by a resistant sole.
