midstance

noun

1. (uncountable)The point in walking at which the raised leg passes the grounded leg that is supporting the body's weight.

   “A camera installed at foot level captured my gait, frame by frame, as I jogged, so the staff could gauge my midstance — when all the weight is on one foot — and determine how much support I needed. Mr. Bergland suggested the Saucony Omni shoe ($100), which is designed for V-shaped feet.”
