Heel Height Conversion The impact of heel height on shoe size:
As necessary as confirming your shoe size – particularly for online ordering – it is also equally important to realize the impact of the heel size to the shoe size you should request. As a rule of thumb you should add half a size to your size selection if the heel is higher than 3 inches.
The truth about the advertised Heel Height Also note that the Heel Height that you see listed for a particular shoe is usually based on the average shoe size for Women. That is still most commonly suggested size 7 ½ to 8. So if your shoe size is less the actual Heel Height will be slightly lower to keep the proportions of the shoe equal. If you have a size of 9 or higher you will experience that the Heel Height is actually higher than the advertised height.
