I picked up the RecoveryPulse Calf to help with tight calves after long runs, and it does the job well. The compression feels snug without cutting off circulation, and the vibration is a nice bonus for loosening things up. I like that it combines compression and vibration in one sleeve, so I can wear it while moving around instead of sitting still. The germanium-infused fabric is a nice touch. It helps with minor aches, though it's not a miracle cure for serious issues. Good for on-the-go recovery.
