The approximate thickness of the midsole cushioning under the heel and the forefoot. A thicker heel and greater difference between heel and toe height tends to suit heel-strike runners, while forefoot and midfoot strikers may prefer a minimal drop between heel and toe cushioning.
The drop is the difference in height between the heel and the forefoot midsole cushioning. Traditional running shoes tend to have a 10mm drop or higher while minimalist style shoes are on the lower end of the spectrum.
