General Tips:
- Measure your feet at the end of the day as they're at their largest due to swelling.

What You'll Need:
- A piece of paper larger than your foot,
- A pen or pencil,
- A ruler or measuring tape,
- Socks of the thickness you'll wear with the shoes.
Steps:
- Stand on the paper in the socks you'll wear with the shoes.
- Use the pen or pencil to mark the end of your longest toe and the back of your heel. It's important to measure both feet as their size can vary.

The C135 features a dual layer midsole, utilizing a generous layer of our sustainable CircleCELL™ foam above a stable, rubberized EVA bottom layer. An ultralight, breathable, and fast-drying upper is engineered to excel in the harsh conditions of Death Valley in July. The result is a shoe that offers 42mm of responsive, comfortable cushioning while weighing just 9.2 oz / 262 g (US M9).
The Badwater® 135 covers 135 miles and has a time limit of 45 hours. With a start time late in the evening, running through at least one night on desert roads is guaranteed. Safety is paramount and athletes are obliged to make themselves seen, so the C135 incorporates a highly reflective coating on the midsole to enhance visibility for safer racing beyond sunset.
The TUNEDFIT™ Dual Lacing System offers separately customizable fit for the forefoot and midfoot. Because we know that in the pursuit of distance, feet can swell and change shape, especially in a race with temperature swings as extreme as Badwater® 135, having a shoe that can adapt to those changes on the fly can be the difference between minor discomfort and injury.
