Adidas Hyper Boost Euphoria LT Black Solar Red — Street Speed
The Hyperboost Euphoria is the first everyday sneaker built on adidas' new Hyperboost foam, the evolution of the original Boost. It is derived from the competition Hyperboost Edge, but with a different purpose: the mountain logo on the tongue gives way to the Trefoil, the unmistakable sign that this model belongs on the street, not the track. It arrived in 2026, and the Black with Solar Red is its most aggressive version.
The Hyperboost Euphoria LT — mono mesh and taped reinforcement
The LT variant starts with a very lightweight, breathable one-piece mono mesh upper, with a redesigned forefoot in which taped reinforcement replaces the running model's mesh window for greater support. The Hyperboost midsole runs the full length of the foot. Here, black dominates the construction, while Solar Red appears in the details and branding, creating contrast without overpowering the base.
Materials and technology
- Upper: One-piece black mono mesh with Solar Red accents; taped reinforcement on the forefoot; Trefoil on the tongue
- Interior: Integrated mesh lining; removable insole; sock-like wraparound fit
- Outsole: Full-length Hyperboost midsole, soft and responsive; rubber reinforcements in the high-contact areas
