More Warmth, Less Bulk
The Alphaburly Aero with Solarcore is built to withstand the coldest temperatures, delivering best-in-class thermal performance without the bulk or weight of traditional insulations. Integrated from midsole to upper, it keeps you warm when conditions get serious and moving when the season demands it. Built on the same hand-laid premium rubber over a 5mm neoprene core for waterproof, scent-free durability. The AeroForm™ ETPU midsole returns energy underfoot while the Burly® Trak outsole keeps you planted no matter the terrain. Early season or late, first light or last.
