The main objective of this study is to evaluate the concordance of the variation in systolic pressure indices measured at the toe and ankle after a walking test in healthy volunteers.

Our secondary objectives are:

• to evaluate the concordance between left- and right-side measures: systolic pressure indices measured at the toe after a walking test (healthy volunteers)
• to evaluate the concordance between left- and right-side measures: systolic pressure indices measured at the ankle after a walking test (healthy volunteers)
• to evaluate the concordance of the variation in systolic pressure indices measured at the toe and ankle during the recuperation phase after a walking test (5 and 10 minutes after end of walking test) in healthy volunteers
