New Balance FuelCell Pacer V2 Review: A Race Day Shoe That Executed the Overhaul
The FuelCell Pacer V2 moves from fast-day trainer to full race day option, with 100% PEBA FuelCell foam, a full carbon plate, and a much lower weight than its stablemate.
Introduction
The New Balance FuelCell Pacer V2 has changed roles. Where the previous version was more of a trainer for fast days, this one genuinely earns a place as a race day shoe, best suited to 5K and 10K racing but with enough underfoot for some runners to take further. The first Pacer never won us over, but this version feels like a complete overhaul in the best way possible, executing far better across the board.
Who This Shoe Is For
This is a shoe for runners chasing fast paces: 400m repeats, 5K and 10K races, and potentially longer distances for efficient or lighter runners. The upper is super minimal, with a tongue that is barely there and a light, breathable mesh that fits like a sock. It runs true to size but leans snug and narrow rather than wide and deep, and the toe box is noticeably more dart-like than the generous room New Balance usually provides.
One practical note: one tester experienced some heel rubbing and blisters on a first run straight out of the box for a race. Once the lacing was dialed in, the issue disappeared, and the collar and heel counter do carry light padding. Take a few minutes to adjust the laces before your first hard effort.

Main Strengths
The midsole is 100% PEBA FuelCell foam, the same material used in New Balance’s Elite racing shoe. The stack measures 32.8mm in the heel and 24.8mm in the forefoot for an 8mm drop. Interestingly, that 32.8mm figure comes from a women’s shoe: the Pacer V2 was designed specifically around elite runner Emily Sisson’s size, then scaled from there, rather than starting from a standard men’s size 9.

The ride sits closer to the ground than the Elite, which gives a strong sense of control and encourages quick leg turnover. It has more Vaporfly-style vibes than the Elite’s more substantial, max-cushioned feel, while still carrying plenty of foam. Weight is competitive too: a women’s 7.5 came in at 6.2 oz, and a men’s 10.5 at 8.1 oz (230g). That is not quite Vaporfly territory, but it is at least two ounces lighter than the Elite. A full carbon fiber plate completes the racing package.
Things to Consider Before Buying
The snug, sock-like fit is the main trade-off. If you prefer a wide, deep forefoot on race day, this upper will feel restrictive. The heel rubbing reported by some runners is worth factoring in as well, even if it seems fixable with careful lacing.
On the positive side of the ledger, the outsole carries a lot of rubber coverage, especially across the forefoot, which adds a little extra bounce and protection under the toes. Durability details beyond that were not part of the testing, so it is hard to say more.

Buying Advice
At $200, the Pacer V2 sits at the lower end of the race day shoe market, which makes it an appealing entry point if you want carbon plate performance without a premium flag-ship price. It has already proven itself at the highest level: Emily Sisson set an American record at the Chicago Marathon in this shoe.
For most runners this is a 5K to 10K race shoe and a superb fast-day trainer, and it earned particular praise for warm-weather 400m sessions where quick turnover matters. If you are very efficient or light on your feet, there is arguably enough cushioning here for any distance you want to run, at a lower weight than the Elite.

Conclusion
The FuelCell Pacer V2 is a light, fast, fun shoe that fixed everything the original got wrong. With PEBA FuelCell foam, a carbon plate, a race-ready upper, and a friendly $200 price, it earns an easy recommendation for anyone building a race day rotation or simply wanting a sharp trainer for fast days.
