Compression garments have been around for some time, but it is only recently that runners have been sporting them for performance and recovery purposes as socks. The tightly fitted knee-high sock compress veins, arteries and muscles on the surface of your legs so that blood is circulated through smaller circulatory channels. Some athletes wear compression socks during and after running to decrease muscle soreness and to prevent soft tissue damage.
To get the benefits of compression garments, it’s important to get the right fit. The sock should be compressed tight at the ankle with less compression towards the knee. Measure your calf and ankle circumference rather than your shoe size to achieve the best fit. Too much compression can decrease blood flow not enough offers no real benefit. So, experiment with various garments and see if they help you to recover and or run faster. Definitely recommended for those that suffer calf tightness during after running. Always consult your medical practitioner if you are unsure of the benefits.
