Along with Meredith Michaels-Beerbaum, Petrie has developed a new flexible lightweight jumping boot. Made of soft calf leather with lacing at the instep and a rear zipper down to sole with zipper guard.
We are able in stretching the shaft for about maximum 1,5cm. That means you can't stretch unlimited riding boots. The leather in all his variations, the lining, the place of the zipper determine the results.
