Love running? Then you'll want to step out in the Adidas Own The Run Block 7/8 Recycled Running Leggings (£45) on your next run. These leggings are made from sustainably sourced fabric that is moisture-absorbing due to the brand's "Aeoready technology", and the added mesh leg inserts cool you down out on your strides. In addition to a high-waisted fit, these leggings also feature a drawcord that helps ensure they stay in place no matter your run pace. They have a zip sweat-guard pocket to hold your phone, but if your smartphone is on the larger size, then you might struggle to fit it in. The sizing options are pretty great, too, as they're available in standard, plus, petite, and tall sizings.
