Getting faster normally means you need to upgrade your kit. And for good runners, everything starts with the shoe.

Your running shoe needs to be perfectly suited to your running style. ASICS speed running shoes are tailored for different long-distance races.

But each one is influenced by the same principles, construction and technologies. Here’s a quick guide to what goes in to our speed running range…

The principles
Our range of speed running shoes is designed with 2 things in mind.

The overall construction of the shoe and how it feels when you run. Different designs affect the speed of your gait cycle transition and the position of your foot when it’s on the ground.

It takes a lot of energy to keep lifting your foot from the ground throughout a marathon. The low weight of our speed running shoes makes it a bit easier.

The construction
How our shoes are constructed is crucial to their performance. The way they’re put together is especially designed to help you go faster.

The midsole in our speed running shoes is lower to the ground. Your foot gets better feedback from the ground and that improves your energy transfer.

It’s the difference in height between a shoe’s forefoot and rearfoot. A low heel gradient promotes faster foot movement and gives you a more dynamic running style.

The technology

Our speed running shoes are built with 2 technologies that improve the shoe’s performance.

The midsoles in speed running shoes are made of this very light and durable material. Lower weight gives you an improved ride – that cushions the impact forces and minimises excessive muscle activity.

This special element is placed in the forefoot to stabilise the shoe and improve your mid-stance. It gives you an improved push-off since energy is transferred to the front of the foot more efficiently.
