Brooks Men Adrenaline GTS 21 – Review

When choosing running shoes, the first thing you should do is know your running style. Afterward, it’s a matter of finding out what type of race you want to use the shoes for; are you a beginner, is it for marathon training or e.g., intervals or maybe trail running? It is not a good idea e.g. to choose Brooks Men Adrenaline GTS 21  just because they look good or you have heard that they should be the best.

Also when we talk about running style, it’s about the way you run because mainly you can have one of three types of feet as the first thing. Your gait can show a pattern of neutral pronation, overpronation, or supination – very precisely.

You can’t immediately see which one you have. But you start by taking a look at the sole on your old shoes and see the way you slip on the sole – how is the pattern? That can give you an idea of your running style and the way you run.

Running Style

Neutral pronation: The shoe that fits this pattern of movement cushions the shock when you hit the ground and supports your foot in its natural movement.

Overpronation: This shoe also cushions shock when you hit the ground. But by overpronation rolls your foot too much inward and this roll must be stopped, to control the foot in the most natural performing of contact with the ground to avoid injuries. Brooks Men’s Adrenaline gts 21 Running Shoes is mainly in this category – and is often called the runner’s pronation favorite.

Under pronation or supination: When the foot under-pronates or supinates it maintains so the run performs on the outside of the sole. In this case, your foot will be controlled so it rolls inwardly as close to the neutral pronation as possible.

This model is great for overpronation. Overpronation is not ‘dangerous’, but with the wrong structure of the running training and too unstable running shoes, it can be a dangerous cocktail in relation to injuries, especially if you train a lot and on long demanding runs.

Often, overpronating runners will tend to classic running injuries such as shin splints and Achilles tendon inflammation as well as pain around the knee. It’s all types of runners that may tend to overpronate, but there are more women than men due to women’s anatomy.

What to look for is whether the running shoe is fitted with a pronation wedge or another braking device on the inside of the midsole and whether it has a fixed heel cap and a secure hold in the upper. The shoes must still be flexible in the heel. It helps to provide a more natural movement.

Today you can have your running style checked on a treadmill in many sports shops.
