While moderate cushion eases the stress on your feet, too much can disrupt proper barefoot technique and increase joint impact.
Choose moderately cushioned footwear if you tend to have foot pain.
Get minimally cushioned footwear if you have strong feet but tend to suffer from joint pain.
Our Alpha model is a great sweet spot for most people switching to minimalist footwear. It provides the perfect balance of cushioned protection, while minimizing disruption to running form.
