Nike Air Zoom Structure 18 Road Running Shoes - Women's

Some shoes include added motion control or stability features to help minimize over pronation, where the foot tends to roll inward in a biomechanically imbalanced running position.

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.

Waterproof shoes and boots feature a waterproof-breathable membrane and a gusseted tongue to help keep your feet dry in wet conditions.
