New Balance FuelCell Rebel v4 vs New Balance FuelCell Rebel v5

The New Balance FuelCell Rebel v4 and New Balance FuelCell Rebel v5 share the same lineage, but the v5 marks a clear shift toward a more cushioned, mainstream daily trainer feel. The Rebel v4 is lower to the ground, firmer, and more responsive, making it a go-to option for runners who want a stripped-down, exciting ride when training. The Rebel v5, on the other hand, adds more stack, a softer midsole feel, and greater upper padding, making it plusher and more forgiving, especially on easy or recovery days. On the other side, it's about 20 grams heavier. For runners who love the v4's raw, fun feel, the update might feel like a step away from its original intent. For those looking for a more comfortable, cushioned version of a (relatively) lightweight trainer, the v5 broadens its appeal.
