The Addiction 14 features our new Heel Segmented Crash Pad that provides a smooth transition from heel to toe. We continue to use our Extended Progressive Diagonal Rollbar (PDRB), which is a support system for your entire body. It strategically positions arch support to guide and keep your body in its natural path of motion. Continuing our use of BioMoGo DNA, our proprietary cushioning, adapts to your stride, weight and speed. This can help protect you by reducing impact on your joints. The Addiction 14 has a generous fit that allows a little extra room to move around in, placing orthotics, or space for the shape of your foot.
