The upper has been crafted from a combination Kangaroo and synthetic leathers which allow this boot to be lightweight, comfortable and breathable. At the forefoot, the last is shaped to be more lightweight, while at the rear the last enhances stability and durability. These boots are constructed from a lighter weight midsole compound than ASICS standard EVA and SpEVA. This Solyte 65 midsole provides a material for a firmer and more stable platform feel. A 10mm heel gradient shifts body mass forward reducing strain on lower limbs. A six screw in studded sole unit grants traction on good to soft ground surfaces.Shipping Restrictions: Unavailable for shipping to Australia.
