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 Hoka Mach 6 is one of the best value do-it-all trainers going, a lightweight road shoe that punches well above its £140 price. It sits in that useful middle ground between a soft daily trainer and a firm racer, so it can handle your easy miles in the week and still come alive when you pick up the pace on tempo day. At 232g with a 5mm drop it feels quick and unfussy underfoot, and the bouncy supercritical foam gives you a lively toe-off without the harshness of a plated racing shoe. There is no carbon plate here, which keeps the ride natural and forgiving. We rate it as a genuine one-shoe solution for runners who want a single pair for most of their training. If you are chasing a marathon PB you will want a plated shoe on race day, but for everything in the build up the Mach 6 is hard to beat. The Mach 7 refines the formula, though the 6 is often the smarter buy on price.
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.
