The Noosa Tri 16 is Asics at its most playful: a light, lively tempo running shoe with triathlon roots and a deliberately loud look. At 215g with a low 5mm drop, it sits in that sweet spot between a daily trainer and a racer, the kind of shoe you reach for when an easy run turns into a fartlek and you want your feet to feel quick. There is no carbon plate here, so do not expect supershoe propulsion. What you get instead is honest, connected speed: a firm, responsive ride that rewards a forefoot or midfoot strike and turns over fast. The tri heritage shows in details built for racking transitions and shrugging off water, which also make it a genuinely fun stripped-back trainer. We rate it as a speed-day shoe for runners who already have a cushioned daily trainer and want something snappier for tempo work, strides and shorter races. It is not a do-it-all shoe, and it is not trying to be.
The FuelCell Rebel v4 is New Balance at its most fun: a lightweight, plateless tempo shoe built to make quick running feel easy. At 212g it is properly light, and there is no carbon plate here, so the pop comes straight from a soft, springy FuelCell midsole rather than a stiff propulsion board. That makes it one of the more versatile speed shoes going. You can rip a session in it, float through a steady long run, then use it as a do-everything daily trainer the next morning. It sits in that sweet spot between a cushioned daily and a race shoe, and it does it for a fair RRP. If you want a single pair to cover most of your mileage without buying a rotation, this is a strong pick. The newer Rebel v5 has since arrived, so the v4 is often the smarter buy on price. Just do not expect the locked-in, aggressive feel of a plated racer. This one is about bounce and freedom, not rigidity.
A side-by-side comparison makes the trade-offs between two running shoes easy to see, but the right pick still depends on how you run. Weight and stack height shape the feel underfoot: a lighter shoe with a lower stack feels nimble and fast, while a heavier, taller stack gives a softer, more protective ride for long miles. Heel-to-toe drop changes where you feel the load, with lower drops asking more of the calves and Achilles.
The price figures update from the UK retailers we track daily. The best price now is the cheapest tracked price we can currently link to, the 90-day low shows how cheap the shoe has been recently, and the 30-day average tells you whether a price is a genuine drop or just the going rate. Coverage is partial rather than complete, so always confirm the final price and your size on the retailer site, and set a price alert on the model you want so we can email you the moment it drops.
