If you're looking to try out compression to help with nagging shin splints or achy calves but aren't crazy about the idea of wearing extra fabric while you race, we'd recommend trying 2XU's Compression Calf Guards as a more minimal option. Lightweight PWX FLEX compression fabric provides support while remaining flexible and breathable, making the calf guards easy to fit under a wetsuit. They work to stabilize the calf muscles and limit the muscle oscillation that can cause shin splints and soreness as you run or ride, without the more aggressive coverage of a full compression sock.
