Feel
'Minimal and natural' shoes offer low drop, lots of flex, and minimal cushioning. Most running shoes are 'Light and responsive' with medium cushioning and good energy return. 'Cushioned and floaty' shoes have maximum cushioning. |
Light and responsive |
|
Stability
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. |

Heel-to-toe cushioning
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. |
21-21mm |
|
Drop
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. |
0mm |

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