Tune Up Fitness

Barefoot brand from USA.

Tune Up Fitness is a US company best known for its Yoga Tune Up and Roll Model therapy balls, which you can roll under your feet or use on other parts of the body. They also offer self-massage videos, online courses and teacher trainings. They don't make shoes, so I see them as something to use alongside barefoot footwear.

Specialities: massage balls, foot massage, self-massage, videos, courses
