The Brooks Adrenaline GTS 20 for men are running shoes for overpronators. One of the most popular shoes for overpronators has been given a few updates. One of these updates has made the shoe lighter in weight. This was achieved by changing the material used in the upper to Engineered Mesh material. Another noteworthy thing is that the offset has a drop of 12 mm for both men and women, which is similar to that of its predecessor the GTS 19. The decorations seen in the GTS 19 have been left out of the new version to keep the upper flexible and to provide the foot with more freedom of movement. The forefoot has been given a bit more room in this model to ensure that the upper encloses the feet without becoming too rigid. The soft heel collar offers comfort and support.The midsole is made of a combination of BioMoGo material and DNA LOFT. The DNA LOFT material is found at the heel. This ensures a soft landing and effective shock absorption. The BioMoGo material is used over the full-length of the foot. This responsive cushioning material returns energy with every step you take. The Adrenaline GTS 19 GuideRails technology is also used in the Adrenaline GTS 20. This technology provides support to the knees when they tire by guiding the feet through their gait cycle. It gives you the support that your body needs. The GuideRails have been added to the shoes differently, which makes the transition even smoother.
