Sinister

Racing2023 · US/Global · ReleaseChecked 2026-11-10

Sinister is a lightweight racing flat for fast road efforts, including 5K and 10K races. Its low-profile PWRRUN PB cushioning uses PEBA foam without a plate, keeping the construction flexible. A pared-back upper reduces bulk and provides a snug, spike-like fit with secure lockdown. The emphasis is on a minimal racing build rather than a thick platform or plated propulsion.
