SC Elite 4 vs SC Rebel 1

The New Balance SC Elite 4 is a full-fat carbon marathon racer, and it wears that brief proudly. This is a tall, soft, aggressively cushioned racing shoe built to keep your legs alive deep into the back half of a marathon rather than to feel featherlight off the line. At 237g it is on the heavier side for a carbon racing shoe, so it does not have the darty, snappy feel of a lighter racer like the Nike Vaporfly 4. What you get instead is a big, forgiving platform and a rolling, momentum-holding ride once you are up to pace. With a 4mm drop and a full carbon plate it sits firmly in the marathon-and-half super-shoe class. At £280 RRP it is a premium buy, but for a runner who wants cushioning and protection over knife-edge sharpness, it is one of the more comfortable ways to race a long road event.

The SC Rebel is New Balance's carbon-plated super trainer: a running shoe built to handle your long runs and faster sessions during the week, then line up with you on race day. It pairs Infinion foam with a carbon plate on a 40mm heel and 36mm forefoot with a 4mm drop, and at a listed 218g it is light for a shoe with this much underfoot. Put the numbers next to the SC Elite 4, New Balance's marathon racer, and they read almost identically: same stack, same drop, and the Rebel is listed lighter. At £180 against £280, that is the story. In our view it suits runners who want one plated shoe for tempo work, marathon-pace long runs and the race itself, rather than an expensive racer saved for a handful of days a year. It is not an easy-day shoe or a stability shoe, and the low drop asks a lot of your calves.
