Confused by all those acronyms, different soles and drops? This is our Run Glossary, to help you out with all the technical running jargon.
Heel to Toe Drop (sometimes referred to as Stack Height): This is the difference in midsole height between the heel and forefoot. In simple terms, how sloped the shoe is. If there is no difference, this is known as a Zero Drop.
Zero Drop: Zero drop or shoes with a low drop, will suit runners who land more towards their mid to forefoot, or who simply would like a shoe that has a more natural feel.
Pronation: Pronation begins as the heel impacts the ground it is then followed by the inward roll of the foot as the arch moves towards the ground, this the body’s natural way of absorbing impact shock and is an essential part in the movement of running. Depending on how much you roll inwards will determine if you are a neutral, over, or under pronator.
Neutral: A runner with neutral gait will pronate to a normal degree.
Gait: Gait refers to the way you walk or run, and everyone will have a slightly different gait. Looking at your gait will determine if you are a neutral runner, over or under pronator.
Cushioned: This refers to shoes designed for a neutral or under pronators, they will be cushioned to help absorb the impact forces experienced while running.
Stability: Stability refers to shoes designed for over pronators, helping to reduce excessive inward rolling of the foot, they will do this without any discomfort to the wearer and also contain cushioning to help absorb the impact forces experienced while running.
Toe box: The section of the shoe which your toes fall into! A wider toe box or going up in size will allow for more wiggle movement, and help to reduce friction on the toes during longer runs.
Upper: This refers to the material that encloses your foot and helps to provide a secure fit. It’s the part of the shoe that everyone sees first!
Outsole: This is the area that the majority of people know as the sole of the shoe; the hard rubber that makes contact with the ground and provides grip.
Midsole: The area between the upper and the outsole that’s mainly responsible for the shoe’s cushioning. The majority of midsoles are made from foams, however some have additional cushioning elements such as air and gels.
