Why should you trust me in case of a fight? Well, I once ran the equivalent of 67 marathons in 67 days with a 25-pound backpack. This is my toolkit for anyone trying to escape pain.
Apply oil: Anti-chafing products like petroleum jelly or special balms are your best anti-chafing protection. Even if your carefully chosen clothes let you down, a generous coating of lube can save the situation. You can't afford to be shy. Especially on the ground floor. You want to make sure you're also visiting places you rarely visit.
be comfortable: I choose shorts, leggings, base layer shorts, tees, and running underwear that are either seamless or have flat-lock seams. I always check the seams of built-in twin shorts and I rarely trust the inner-briefs built into regular shorts. If in doubt, wear your trusty undies.
tightening: I choose tight layers that hug the body rather than loose-fitting gear. It seems counterintuitive but clothing that stays in one place, close to the skin, works better than loosely hanging clothing that moves around more.
avoid cotton:Cotton is heavy and can be abrasive even when dry. When it gets wet with salty sweat, it's a disaster for your tender organs. Layers that touch your skin should be made of synthetic or woolen fabrics. They dry faster and reduce friction.
Powder your toes: The blisters have essentially atomized and may be difficult to avoid. Applying powder to my feet and socks can help reduce moisture which increases the risk of rubbing and hotspots.
