Inspired by Fear
One of Ja's all-time favourite film characters has haunted dreams for decades. This special design channels that terror—the feeling of being chased, hunted and never safe. The same fear defenders feel when Ja turns the corner.
Benefits
- The rubber outsole adds durable traction.
- The soft foam midsole helps provide lightweight cushioning.
- The CPU upper offers amazing durability for lightweight support and lockdown. The JA-frame wraps around the midfoot to help keep you contained for extra stability while staying shifty.
