2TOMS BLISTER AND CHAFING PREVENTION

SportShield is the broadest anti-chafing option for areas such as thighs, groin, nipples, underarms, bra lines and clothing or equipment contact points. It forms a waterproof and sweatproof barrier over the skin to reduce friction while allowing normal perspiration.

SportShield XTRA provides the same general-purpose anti-chafing protection but adds shea butter together with calendula, green tea and horsetail extracts. Choose XTRA if you want the SportShield approach with additional skin-care ingredients; choose standard SportShield if you prefer the simpler formula.

ButtShield performs a similar job but is specifically formulated for sensitive, high-friction areas, particularly the inner thighs, groin and buttocks. It is also waterproof and sweatproof, with shea butter and plant extracts included for this more sensitive role.

BlisterShield is different. It is a waterproof, moisture-repelling foot powder that reduces friction inside the sock. Unlike a conventional powder that primarily absorbs moisture, it is designed to repel moisture without clumping or turning into a paste when wet.

SportShield, SportShield XTRA and ButtShield are best applied before rubbing becomes a problem. Apply a thin covering to clean, intact skin where you know chafing is likely. They are designed for prolonged activity and can be reapplied during an ultra if experience shows that you need it. They are preventative products rather than treatments for cracked, bleeding or otherwise damaged skin.

BlisterShield should be used on clean, thoroughly dry feet and inside the socks before running. Pay particular attention to recurring problem areas such as heels, between and around the toes, the forefoot and ball of the foot. Around one level teaspoon per sock is the manufacturer's guidance for the full-size powder.

SportShield, SportShield XTRA and ButtShield can be removed after use with soap and water. A dry towel can help remove any remaining product.

The full-size SportShield, SportShield XTRA and ButtShield roll-ons and BlisterShield powder are the practical choice for regular training, pre-race preparation and repeated use. They can also be kept in a drop bag or crew kit during a longer event.

SportShield, ButtShield and BlisterShield are also available in corresponding single-use formats. These are useful when you want protection with you between checkpoints and take very little space in a race vest, waist belt, shorts or jacket pocket. SportShield XTRA is currently available from UMRS only as the full-size roll-on.

Yes. 2Toms products can help protect the skin or reduce friction and moisture around the feet, but they should not automatically replace looking at why a recurring problem is happening.

Clothing fit, seams, a moving race vest, footwear, socks, moisture and repeated movement can all contribute. If the same hotspot or rubbing point keeps returning, use training to identify the cause and test changes deliberately. See our blister and chafing guide for the broader ultra-running approach.
