Shop Flame 5 Future- Midsole
- CQT EXTREM3 block-foamed PEBA: high rebound and soft. The foam is 40C above the plate and 43C below it. Large areas of foam are removed where they are not needed, to keep weight to a minimum.
- Stack
- 36mm heel / 30mm forefoot
- Weight
- 200g in sample size US 8.5
- Plate
- Carbon plate in a single plane, rather than the dome of the regular Flame 5, which makes it World Athletics legal. The design is more "bottom-loaded" than Flame 4, with a deeper scoop in the forefoot that puts more foam between you and the plate.
- Outsole
- RPU rubber with less coverage than Flame 5, to reduce weight.
- Upper
- New engineered single-layer mesh for lightweight breathability, with a heel pull loop for a quick fit.
