ASICS Metaspeed Sky Tokyo

Straight answers

Is the ASICS Metaspeed Sky Tokyo legal for road racing?

Yes. The ASICS Metaspeed Sky Tokyo measures 39.5mm at its highest point, 0.5mm inside the World Athletics 40mm road limit. The limit only binds Applicable Competitions; most club and local races apply no shoe rule at all.

How much does the ASICS Metaspeed Sky Tokyo weigh?

170g in a men's US 9 (UK 8), by the manufacturer's stated figure. Weight moves roughly 3.5% per UK size step, so a UK 11 weighs materially more than the spec sheet says.

What is the stack height and drop of the ASICS Metaspeed Sky Tokyo?

39.5mm at the heel and 34.5mm at the forefoot — a 5mm drop. A carbon-fibre plate runs through FF Leap over FF Turbo+.

How long does the ASICS Metaspeed Sky Tokyo last?

We estimate roughly 250km of competitive life — the point at which the foam has degraded enough that you are no longer getting the benefit you paid £240 for, not the point at which the shoe falls apart. Spread over race cycles, that is what the cost-per-race figure on this page is built from.

Is the ASICS Metaspeed Sky Tokyo good for a marathon?

Yes — the marathon is one of the distances it is built for (10k, half marathon and marathon). For stride-length runners — the Sky is built to let your stride open up rather than turn over faster. Arguably the best all-round marathon shoe currently made.
