BlisterShield foot powder is a high tech solution that prevents blisters, chafing and other types of skin irritations. BlisterShield creates an almost frictionless surface, reducing heat build up and blister formation. The powder does not absorb moisture, rather repels it, keeping the skin relatively dry similar to clothing made of 'high tech' synthetic fibers that wick moisture away from your skin, rather than absorbing moisture like cotton. Dramatically reduces friction. Shields the skin without forming a sticky coating. Remains effective over long periods of activity. Allows moisture transfer through the skin. Not affected by moisture.
