Hi so i was in a big class last week with a new couple teaching us, and they said to "roll through the heel". Before I was just plonking my foot down flat as I stepped back, but now they want us to lift the toe a little bit right after the heel strike. At the moment Im trying to get used to it, and its ok, but as the toe comes off the ground i tend to wobble a bit, i mean I know moving backwards is ok, but I'm moving side-to-side a bit too. which isn't so good I'm thinking My dancing shoes arent high according to the box there about 3,5cm=1.5in. WOuld it be better to have higher shoes would i get less of the side to side motion? and easier to lift the toe?
