New Balance Womens FuelCell Rebel V5 - Responsive (Style K99Q)

Our review of the New Balance Womens FuelCell Rebel V5 finds it best suited to runners and trainers who want a lively, lightweight daily shoe with a noticeably propulsive feel. The single biggest reason to buy is the FuelCell foam midsoles, which deliver a springy, forward-driving ride that adapts well from steady long runs to shorter, faster sessions. The shoe balances a race-inspired look and a comfortable fit, making it a reliable option for women seeking an everyday trainer with a bright, bouncy character.

Key Features

• FuelCell foam: Provides a propulsive, responsive underfoot feel that helps drive the stride forward on both street and treadmill runs.
• FantomFit upper: Offers ultra-light bonded support that holds the foot securely without adding weight or bulk.
• Geometric midsole: Extends wider and stacks higher than the previous version to increase stability and a cushioned ride.
• Gusseted tongue: Keeps the tongue centered and reduces pressure points for a more comfortable training session.
• Longitudinal outsole pods: Improve traction and flexibility for road running and varied paces.

Who It's For

The FuelCell Rebel V5 is ideal for recreational runners and gym-goers who appreciate a lively, lightweight trainer that performs across paces. It suits heel strikers and neutral runners who value cushioning with a springy rebound and a streamlined, race-inspired mesh upper.

Runners who need a very roomy fit or maximal long-run durability under heavy weekly mileage may want to consider more cushioned or stability-focused alternatives. Those needing a highly structured support system for overpronation should look elsewhere.
