Topo Athletic Ultrafly 5: cushion, light stability and a roomy fit

The Topo Athletic Ultrafly 5 is a cushioned stability road shoe for daily kilometres and walking. It's for runners and walkers who want a little help keeping things aligned, plus a roomy, foot-shaped toe box, without massive stacks, carbon plates or super-trainer hype. The Ultrafly 5 has been replaced by the Ultrafly 6, so sizes in the 5 are limited.

What is the Topo Athletic Ultrafly 5?

The Topo Athletic Ultrafly 5 is what we call a "do-everything stable trainer." It pairs a modern midsole with a foot-shaped fit and light pronation support, for a ride that feels smooth, secure and natural.

Key specs:

• Stack: 30 mm heel / 25 mm forefoot (5 mm drop)
• Weight: 281 g (9.9 oz) men's US 9; 228 g (8.0 oz) women's US 7
• Midsole: ZipFoam (an EVA/TPU blend), with more cushioning than the Ultrafly 4
• Support: a medial post and an external TPU heel counter for light pronation support
• Insole: OrthoLite Performance
• Upper: recycled engineered mesh with a wide toe box

In short: a stable, cushioned, foot-friendly shoe built for everyday kilometres and comfort.

How does the Topo Athletic Ultrafly 5 feel on the run or walk?

The Topo Athletic Ultrafly 5 feels balanced and steady: supportive without over-correcting, with medium cushioning that's comfortable but not mushy.

A stable, smooth ride. The medial post and heel counter give gentle guidance, which suits daily runs, easy kilometres and recovery days.

Room for your toes. The wide, anatomical toe box lets your toes spread out without feeling cramped.

Cushion with some ground feel. ZipFoam isn't max-cushion soft. It strikes a balance: enough softness for comfort, enough firmness to feel efficient.

A "life shoe" too. Topo Athletic builds it for daily runs and walking, and it works for easy kilometres, a walk along the harbour front or a day of errands without switching footwear.

Who is the Topo Athletic Ultrafly 5 best for, and who should skip it?

The Topo Athletic Ultrafly 5 is best for runners and walkers who want light pronation support and a roomy toe box in one versatile shoe. It's a dependable everyday pair that punches above its price.

• Good fit: runners looking for a reliable daily trainer for easy runs, recovery and moderate kilometres; walkers and anyone on their feet a lot; people who like a natural foot shape and toe splay; runners who want a touch more structure from a medial post and heel counter; anyone who'd rather own one versatile pair than several specialists.
• Skip it if: you're chasing PRs or speed work (it's not a racer or fast trainer), you want more cushion for long runs (look at the Ultrafly 6), or you have narrow feet and prefer a snug fit through the forefoot.

Ultrafly 5 vs Ultrafly 6: which should you choose?

Choose the Ultrafly 6 if you want more cushion, an updated heel-wrapping medial post and more rubber underfoot; choose the Ultrafly 5 if you like its slightly lower stack and can find your size. Both keep the 5 mm drop and wide toe box.

How does the Topo Athletic Ultrafly 5 fit?
