Radiantly Slim Running and walking barefoot
Running barefoot or in minimalist shoes corrects posture errors and also strengthens the ankle especially if one chooses an uneven or very flexible ground like sand or dirt roads. It is good to alternate walking and running slowly in very small strides and to insert some specific walking exercises. For example during the walk we will take care to completely unroll the foot to finish in full extension on the toes.
