Stay cool with these shorts. I recommend shorts made of wicking fabric to dry quickly and keep you cooler. Bike-style shorts with lycra can help prevent chafing. If you use arm motion, it is best to select shorts without side pockets so you won't catch your thumbs.

I've been wearing these as my performance shorts for a few years. The fabric is quick-drying and ultralight. They have a 3 1/2-inch inseam and a notch on each leg to allow free leg motion. Sizes small to XL.

I really like the look and design of these shorts. They have a beefier waistband than most sports shorts, with contrasting lacing. The back zip pocket is very useful for small essentials, and you won't risk hooking your thumbs on side pockets when you are using good arm motion while walking. It has a liner so you can choose to wear additional undies or not.

When you don't want to show off your knees, but still want great comfort, I love the Brooks Energy Capri. The polyester and spandex fit well but not tight, and they bell out at the hem so your legs aren't squeezed. I love walking in these in spring, autumn, and cooler summer days.

Want to feel a little more feminine while still having the benefits of wicking fabric and compression shorts? This skort has a skirt over compression shorts, with slits in front for easy motion. And all the benefits of just having one waistband instead of two.
