Care Instructions
- BRUSH ME, WASH ME: Rinse boots after each use. For a deep clean, use water and mild soap with a soft brush. Let air dry away from direct heat.
- OIL ME: Apply a rubber conditioner or natural oil once dry to maintain flexibility, especially at flex points (toe and ankle). We recommend the Revivex Rubber Care Spray available at grubswarehouse.com.
