Vivobarefoot Primus Lite

May find it useful

Adults who deliberately want to try a wide, thin and flexible training shoe and can introduce a different loading pattern gradually while monitoring comfort.

May not need it

People whose current shoes work well, anyone expecting an automatic strength or injury benefit, or readers with symptoms or circumstances that require individual footwear advice.
