In the past few years, we have covered plenty of high quality foot massagers here that help athletes recover faster. The Zimmo Freefoot is also worth a look. It is a portable foot massager that you can use anywhere to relax. It has a cordless design and offers full foot coverage.
Zimmo is pretty easy to use. Just slide your feet into it like you would with your shoes, and you are set. It has 3 massage settings and 4 massage modes. It uses 36 massage balls for the soles of your feet, 5 for under the arch and 2 massage heads for the heels.
