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.

Based on the highly respected R2V2, the next-generation R2 3.0 takes the benchmark in compression apparel to a new level of performance. The Flash model adds fluorescent panels and reflective details to enhance your visibility, regardless of the time of day. Seamless multi-conductivity compression, quick-drying fabric, and a shock-absorbing K-Protect knee tab are complemented by innovative Fibular Stripes that activate proprioception and enhance balance and stability, meaning fewer twists and sprains on the trail. Just like previous generations, these high-stretch sleeves stimulate blood flow, preparing your muscles and mind for pre-activity efforts. During training and racing, they absorb vibrations to help limit muscle damage, reduce pain, and delay fatigue. Targeted horizontal waffle knit zones promote microcirculation and lymphatic flow, reducing shin splints and inflammation during high-mileage workouts. And after learning about a recent scientific study that showed compression sleeves can reduce stomach discomfort after strenuous exercise, we refined these knitted waffle zones to further promote blood flow and reduce gut damage. In short, no more stomach-cramp-induced DNFs. Seamlessly comfortable for zero irritation, the top and bottom hems get a striking high-visibility touch in fluorescent yellow. They're complemented by reflective logos and details on the front and back to ensure you stay safe and seen in urban environments or low-light conditions. Soft, ergonomic, and designed for ultimate support and performance, the R2V3 Flash is ready to light up any run; from the local park to the Western States.
