Use the Performance Sole/Heel chart to gauge which combinations will give you optimal sliding and braking for your style of delivery.Replacement Soles

Because you brake with your heel, use a heel with more friction (a lower number) than the sole. Otherwise, you won’t have adequate slide-brake action. An exception would be if you bowl best with a heel that has the same number as the sole. Using a higher heel number than sole number is possible but not recommended for general approach conditions.
When changing either the soles or heels of your performance shoes Storm recommends that you use caution when trying the new combination for the first time. Taking several practice slides on the approach without holding a ball will allow the bowler to predict how the reconfigured shoes will slide on the current approach conditions before throwing the next ball.
When attaching a sole to the performance shoes make sure that the sole’s leading edge is first butting against the front of the toe bumper. Note that the toe bumper will extend down slightly over the sole edges thereby protecting the leading edge of the sole from peel-back.
