Power every step with support that works as hard as you do. Now available at Alamo Shoes in Chicago, the Aetrex L420 Compete Posted Orthotics are your go-to solution for low arches, flat feet, and active lifestyles.

Engineered for serious comfort and performance, these orthotics feature a tri-density design that redistributes weight, absorbs shock, and delivers all-day stability. The CopperGuard® top layer provides antimicrobial protection while wicking moisture to keep feet cool, dry, and blister-free. Beneath that, a layer of Pro-Shox® polyurethane cushions each step, reducing impact whether you’re walking, running, or hitting the trail.

With a posted heel to control overpronation and enhance balance, the L420 is ideal for anyone dealing with arch pain, plantar fasciitis, or heel discomfort.
