When changing either the soles or heels of your SST shoes Dexter recommends that you use caution when trying the new combination for the first time. Using a higher heel number than sole number is possible but not recommended for general approach conditions. An exception would be if you bowl best with a heel that has the same number as the sole. Otherwise, you won’t have adequate slide-brake action.
Because you brake with your heel, use a heel with more friction (a lower number) than the sole.
