Swiss company Compressort has an extensive clothing line for trail runners. Most items are fairly close-fitting.
Size advice Compressport
First, a bit of general advice. For socks and non-compression products: choose your normal size.
For compression products: If you're between two sizes, always choose the larger size. Don't worry! You'll still benefit from the compression. Your muscles swell during exercise, and your size should allow for a certain margin to prevent a tourniquet effect and thus restricting blood flow.

The lightest compression calf sleeve on the market, offering minimal weight and maximum support for the most extreme conditions
From the lava fields of Kona to the scorched sands of the Sahara—some races demand nothing less than the ultimate in performance gear. Luckily, we created the R2 Oxygen compression sleeve. Developed as an ultralight version of our iconic R2v2 compression sleeve, crafted with long distances and extreme conditions in mind, this isn't just the lightest calf sleeve we make… it's the lightest calf sleeve on the market, weighing in at just 15g.
Quick-drying mesh panels provide 360° ventilation, while the ultra-soft, lightweight yarn feels like a second skin, so you'll barely notice you're wearing them. But that doesn't mean we've compromised on comfort, support, and everything that makes our R2 sleeve so popular.
The ultra-thin fibers are proven to retain all their compression properties, providing optimal calf support while minimizing muscle vibration and damage. For added comfort when you need it most, those ventilation stripes on the back of the sleeve are gradually positioned to expand with your muscles as they swell during prolonged efforts. And for those running after dark, we've also added a reflective logo to the back of the sleeve. When the heat is on and the clock is ticking, you'll be glad you're wearing the feather-light R2 Oxygen sleeve. After all, if it's good enough for Fred Van Lierde...
