The foot/ankle complex is well supported within the boots providing relatively good structural control, however if you have a pronated or supinated foot position this can translate into unwanted rotation which acts on the whole mechanics of the body. Also, with the feet being relatively static within the boots, this can create localised high pressure underneath the feet creating a burning sensation and pressure under the balls of the feet.
