I am happy with my purchase of the 2XU Aero Hi-Rise 4 Inch Shorts. I bought them specifically for running and have already taken them out on long runs up to 22km with absolutely zero chafing. The design is excellent. They are truly high-waisted, which I love, and the 4-inch length is the perfect sweet spot-short, but not too short. The storage is highly functional for distance running: there is a small internal pocket for keys and a back pocket that easily holds 1–2 energy gels. I bought two pairs (one in black and one in navy blue) and the colors are deep and solid. Sizing note: I initially ordered size M, but preferred a slightly looser fit, so I exchanged them for a size L. The exchange process through 2XU was quick, easy, and returns were completely free! They fit beautifully now. Highly recommend
