TYR Valkyrie Elite Carbon vs New Balance SC Elite V4: Marathon Racer Head-to-Head

Introduction

With a spring marathon on the calendar, we put two of the top carbon marathon racers through a back-to-back marathon-pace workout: the TYR Valkyrie Elite Carbon and the New Balance SC Elite V4. Both shoes were tested in the same session, one 5-mile block at marathon effort each, to see how they compare where it matters.

Why These Two Racers Are Being Compared

The reason for pairing these two is stability. Both are among the most stable marathon racing shoes available. Set next to a Vaporfly, the TYR platform is noticeably wider at the heel, and the launch PX foam, which is very similar to Saucony’s Power Run PB foam, feels more supportive and structured rather than squishy. That kind of platform and structure matters for runners who want a racer that does not feel squirely underfoot.

Weight and Fit

In this pair, the SC Elite V4 came in at 266.5g on the right shoe and 268g on the left, in a size 11, which is a half size above the tester’s typical racer size. Scaled to a 10.5, that works out to roughly 260g. The first pair in size 10 was too tight, and the larger size provided much better toe room and a comfortable, decently wide fit.

The TYR, tested in a 10.5, fits a little more dialed in. It sits lower to the ground and flatter, while the New Balance has more of a rocker feel at the back. Sizing note: New Balance shoes can run between sizes, so it is worth trying your usual size and a half size up before committing.

Midsole and Ride Feel

Both midsoles are 100% PEBA, but they feel very different. The TYR’s launch PX foam behaves like the Power Run PB formula used in Saucony shoes: supportive with structure and a plate that gives a clear snap off the forefoot. The New Balance Fuel Cell PEBA is unique, sitting somewhere between soft-and-bouncy and dense, and it needs serious force to come alive.

On foot, the SC Elite V4 is the big, cushioned cruiser: a very tall-feeling stack (it looks and feels taller than 40mm), huge protection, and a ride that really sings once you push down to faster paces. It felt best around 10K to fast-marathon pace in the 6:15 to 6:09 range and awkward and clunky at easy 8-minute-mile marathon paces. The TYR is the opposite character: lower to the ground, nimble, with an aggressive forefoot rocker doing the work and an easier rhythm at steady marathon pace, though it does not feel as cushioned or protective.

Stability, Upper and Outsole

Both are strong on stability. The SC Elite V4 sits higher but the structured foam keeps it from feeling tippy, with no twisted-ankle feeling. The TYR edges it out when cornering and navigating tight turnaround cul-de-sacs, thanks to better heel foam shape and lockdown.

Up top, the TYR has the better lockdown, reminiscent of the Saucony Endorphin Speed 3 but without the pinching, plus more heel padding. The New Balance offers more room in the upper, which suits wider feet, though some runners have reported heel blistering; no hot spots appeared in this testing. Both have structured heel counters, with more rigidity in the New Balance. The TYR also wins on laces, using textured laces similar to the Vaporfly 2’s, while the New Balance’s flat laces run long.

Underfoot, both have similar rubber layouts with a midfoot cutout. The New Balance pushes rubber all the way to the edge and uses an excellent compound that performed well in the rain in other recent models. The TYR leaves some exposed foam at the edge, which is already showing light wear around 30 miles; extended rubber would have added protection. The TYR’s wet-weather performance remains unproven and needs testing.

Which Shoe Is Right for You

The SC Elite V4 is the better pick if you want maximum cushion and protection, run a fast marathon pace, or need a wider platform. It is a genuine race-day contender for taller, powerful runners pushing sub-3-hour paces, but it feels stiff and awkward at slower 7:30 to 8:30 marathon paces.

The TYR Valkyrie Elite Carbon is the pick for runners around a 3:30 marathon pace or anyone who wants a nimbler, more controlled ride. It is priced at $250, the same as the SC Elite V4, which is a tough ask for a less established running brand, but a 10% discount code (SUBWELL) brings it down to $225.

Conclusion

These two racers are closer on paper than they are on foot. The SC Elite V4 is the cushioned, protective tank that rewards speed and power, while the TYR Valkyrie Elite Carbon is the lower, snappier option that excels at steady marathon efforts and cornering stability. Choose based on your pace, your foot width, and how much stack you actually want under you on race day.
