I'm terribly confused I have had many pairs of clarks in motion sandals, they have never done to me what these do; the stitching burns my feet (both on the sole and the upper) after 30 minutes or so, they rub my skin raw and give me blisters on my toes and heels within an hour, the sole of the shoe is hard and doesn't move with my gait like  a good walking shoe at all... are these even real clarks?
