Having endorsed several world-famous runners over the years, it's perhaps no surprise that Nike is one of the most established running brands out there. Available online and in-store, they offer an impressive range of expertly engineered fitness clothing - including running shorts, naturally. Great liner comfort, thin breathable fabric, comfortable elastic waistband sits flat against the skin

Microscopic holes in the fabric make these the most breathable shorts we've tested. These shorts are great for hot and humid conditions without soaking up too much moisture

There are three main types of shorts. The first are looser shorts of various lengths, from very short split shorts to 5in or 7in shorts. These usually have an inner brief to add support in key areas. Then 2-in-1 shorts have the same outer layer, but instead of an inner brief they have a full set of tight, stretchy shorts underneath. Finally, half tights just have the inner layer. The advantage of 2-in-1 running shorts, like Nike's Flex Essential 2-in-1 Women's Running Shorts, is the compression offered by the biker short underneath. This presses against the skin and offers support without being too tight. The lightweight shorts over the top offer coverage and a stylish fit. It's entirely a personal preference from a comfort and style point of view as to whether you wear leggings or shorts. "I would always say to clients and friends, where what you find comfortable," says Ward. "The worst possible thing is being uncomfortable when running, so make this a priority as chafe isn’t fun, nor is hitching up your bottoms." Many people wear men’s running tights in entirely different ways. Some wear running tights by themselves while others wear shorts over or even under them. However, ultimately this depends on the style and make of your running tights.

Unique standout designs that offer a great liner and waistband comfort, these are perfect shorts for tempo efforts with their streamlined designHigh-waisted or on the hips? It's perhaps one of the more undervalued features of running shorts but it can make a big difference, says Ward. "It can change how comfortable running shorts are. I like a short that sits above my hips/on my waist. If you are the same, look for short that has a high waist band in the product description."
