NORDLIGHT Race · Season 26

HALO 1

Carbon around the foot. Not under it.

A carbon rim wraps the foam instead of splitting it. Your forefoot sinks into bare AERFOAM X; the rail catches you at the edges and rolls you forward.

Drag to turn it. Scroll to take it apart.
Rocker

Tip over. Don't push off.

The toe sits 34 mm off the ground. The roll starts at 59% of the length, just behind the metatarsal heads, so the shoe tips you forward at the exact moment your calf would start working.

39 mm heel · 32 mm forefoot · 7 mm drop
Upper

One layer. No stretch.

Monofilament woven into 1 mm hexagonal cells. It doesn't give under load and it doesn't hold water, so the fit at 40K is the fit you laced at the start line.

38 g/m² · 1 mm cell · translucent
Halo Rail

A rim, not a plate.

One continuous carbon rim runs the whole perimeter: heel, both sides, toe. The centre stays open, so the foam under your foot compresses freely and springs back in full. A single keystone bridge keeps the rim square under the arch.

Twill carbon · 1.8 mm · 7.2 mm flange
The stack

Five layers. Nothing else.

Soft foam on top, the rail, firm foam underneath, rubber only where you land and toe off. No heel counter, no insole board, no glue you'll ever carry up a hill.

Assembled

Race day only.

Built for one job: holding marathon pace when your legs have stopped agreeing to it.

The record run

Faster after thirty.

Halden Lakeshore Marathon, 12 April 2026. 6 °C, still air, a flat causeway loop run twice.

“I stopped thinking about my calves at 30K. That has never happened to me in a marathon.”Maren Solvik, after the finish

Solvik ran the second half sixteen seconds faster than the first, and her quickest 5K came between 35 and 40 kilometres. She raced in a pre-production pair with 180 km on them.

Materials

Four materials. Each one earns its place.

Studio renders of the production model, the same geometry you turned above.

Macro of the translucent hexagonal mesh upper with lime lacing

Hex monofilament UPPER · 38 G/M²

Single-layer monofilament woven into 1 mm hexagonal cells. Translucent, non-stretch, unlined. It creases instead of stretching, which is exactly what keeps your foot on the platform in the corners.

Close-up of the AERFOAM X midsole sidewall with the carbon rail band

AERFOAM X MIDSOLE · TWO LAYERS

Supercritically foamed and split in two so each layer can do one job: the top layer is soft for landing, the bottom layer is firmer so the rail has something to push against.

The carbon twill rail flange running along the forefoot sidewall

Halo Rail CARBON TWILL · 7.2 MM FLANGE

A 2×2 twill rim with an upturned flange that shows on the sidewall. Stiff exactly where the foot rolls off and absent where it lands: the centre of the rail is open.

Outsole view: chevron-siped forefoot rubber pad and lateral heel crescent on bare foam

GRIPLINE RUBBER · 1.9 MM

Two pads and nothing more: a chevron-siped forefoot for toe-off and a crescent on the lateral heel for the first touch. Everything else is bare foam you don't have to carry for 42 kilometres.
