There’s a famous story about Sir Edmund Hillary and sherpa Tenzing Norgay’s boots, which they commissioned a year before their ascent up Mount Everest. Back in the 1950s, mountaineering boots were often cumbersome. Many were bulky and heavy, made of thick deerskin leather, and some even came up to the wearer’s thighs – not the kind of boots you’d want for the most challenging mountaineering expedition. So Hillary and Norgay approached SATRA, a British research and development center, about coming up with something that was lighter. As they knew then, a pound on your foot can feel like five pounds on your back. At least when you’re scaling a mountain.
The resulting boots were made using mostly natural materials and some of Britain’s oldest shoemaking techniques. They featured a reverse welt to keep the melting snow from seeping into the boots, and a Tropal-leather insole to allow sweat to dissipate. The uppers were constructed from a Latex-coated glacé kid leather, which was chosen for its weight. Finally, for insulation, the interior cavity was filled with kapok, a natural hollow fiber (the boots had to be specially lasted in order to not crush the material). In the end, the boots weighed two and a half pounds lighter than what the Swiss had worn in 1952. They were the mountaineering equivalent Nike’s Flyknits, and no one who wore them got frostbite – a remarkable achievement.
Few of us will ever face such conditions, let alone stand on top of the world like Hillary and Norgay, but there’s something satisfying about having the exactly right clothes for the weather. During the early weeks of spring, when the weather is stormy, that means a few things. A couple of raincoats for different levels of formality, some insulating sweaters, and a reliable umbrella that won’t invert at the slightest hint of wind. Finally, a pair of rain boots that you don’t mind mucking up.
