Engineered Mesh Upper
Designed using an engineered mesh, the upper of the Aero Blaze 4 GRVL allows cool air to circulate while at the same time removing unwanted warm air, helping to regulate temperature and create a perfect microclimate where feet can thrive. To avoid damp feet and, therefore, dampened spirits, a GORE-TEX membrane supplies durable waterproofing and optimised breathability. Sometimes it’s hard to stay dry without developing that distracting clammy feeling. Still, GORE-TEX keeps water out while letting perspiration escape from the inside, keeping sweat to a minimum and you cool and comfy. The shoes also use SensiFIT technology, which wraps the foot from the midsole to the lacing system, ensuring a secure, snug, and more personalised fit. A soft textile lining increases comfort, while the new quickLACE neo system completes the upper, ensuring a custom and more precise fit.
optiFOAM² Midsole
Using an optiFOAM² midsole, the Aero Blaze 4 GRVL features a lightweight, responsive foam compound for optimum underfoot comfort and outstanding energy return. Softening your landing from road-running surfaces to trail adventures, the midsole adds bounce to every stride, keeping you fast and light. Absorbing shocks when striking changing terrain, the compound prevents discomfort, reduces injury and returns energy to push you toward your next mile. A moulded OrthoLite sockliner moulds to the contours of your feet, providing even more cushioning and adding durability for step-in comfort.
Gravel Contragrip Outsole
Utilising a unique Gravel Contagrip outsole, the Aero Blaze 4 GRVL facilitates seamless transitions between various terrains, optimising durability underfoot while ensuring excellent grip on both gravelly ground and paved roads. It establishes a strong connection with the ground, enhancing the runner’s confidence, and is designed for long-term use and enjoyment. The outsole’s chevron lug pattern digs deep into the ground, offering multi-directional grip that enhances traction on softer surfaces like mud or loose dirt. Drawing inspiration from gravel bikes, it enables confident transitions between different terrains.
