Have you ever thought about what’s actually inside your running shoe? We sliced a Brooks Launch 2 in half to expose five key parts:
A: Flat-Seam Interior
Instead of awkward seams that can irritate parts of the foot, most shoes are designed to have a smooth interior to allow running with or without socks.
B: Engineered Mesh Upper
New, high-tech meshes offer greater durability and stretchiness, but they also provide more support and facilitate a snug, secure fit.
C: Basic Foam Layer
The primary midsole foam in most shoes is generally some form of ethylene-vinyl acetate (EVA) aimed at dampening impact.
D: Secondary Foam
New materials create a softer experience, more energy return and the feeling of forward propulsion at the front part of a gait.
Thickly cushioned sockliners enhance the step-in feel at the try-on moment in a store, and increase comfort on long runs.
