The benefit of compression has been confirmed, both anecdotally and clinically. The Cramer Run line has a number of products designed to keep runners running - here the Thigh Compression sleeve.
Designed with Medical grade graduated compression, the sleeve supports the affected muscles while allowing circulation without hindering movement. The gauzy mesh breathes well and wicks moisture preventing friction or discomfort, while promoting active recovery and full range of motion. Cramer has quite a broad range of products with additional information on their website - http://tandemsport.com/store/brands/Cramer_Run.html
