Altra

Altra shoes are unique in the marketplace because they combine a zero drop sole and barefoot foot positioning with the structure and cushioning of a traditional running shoe. ALTRA's core running and trail shoes come with a complete three-layer cushioning system: a full rubber outsole, a 12 mm fully cushioned midsole, and a 5mm insole. In total, Altra's 21 mm cushioning is on par with durable training shoes and provides two to five times the protection of a typical minimalist shoe. Altra shoes are durable enough for runners to train and complete even ultra marathons in the same pair.
