Newly updated with lighter cushioning, the Adrenaline GTS 23 offers a perfect balance of support and softness that results in a smooth ride for miles at every speed. Lace up and find out for yourself why these running shoes have been runner favorites for over twenty years.The new Engineered Air Mesh upper hugs the foot for a secure fit while also improving breathability. Constructed using a breathable mesh, the Brooks Adrenaline GTS 23 Running Shoes wrap the foot in lightweight support. Perforations within the fabric allow cool air to flow throughout the construction whilst, at the same time allowing hot humid air to escape so you can remain cool, dry and comfortable at all times. The mesh creates a perfect microclimate for your feet to thrive in so you can go further for longer in complete comfort. The Adrenaline GTS 23 supplies the same proven fit as its predecessor whilst also integrating a more streamlined look and more strategic use of 3D Fit Print technology which increases overall comfort and reduces bulk giving you speed and agility mile after mile. The 3D Fit Print applies strategic stretch and structure to the upper. Strategically placed around the heel and next to the lacing system the overlays work to ensure a supportive fit whilst also providing added durability. Completing the upper is a lacing system that locks down the midfoot to reduce in-shoe slippage so you can enjoy distraction-free strides.
