Standard, Wide or Narrow: which DYNALAST 2.0 fit do I need?

Shimano’s advice: if your current Standard Shimano shoes fit well, the new Standard feels familiar at the midfoot and heel with more room for the toes, and if you sized up for width before, try half a size down. The new Wide is significantly wider than the old Wide, so only riders who really need forefoot volume should pick it. Narrow is the closest match for Shimano’s previous women’s models or anyone who wants a snug, lower-volume fit.

S-PHYRE RC910 or RC810?

Both are SPD-SLR road shoes on DYNALAST 2.0 with dual BOA Li2F dials, and both come in Standard, Wide and Narrow. The RC910 adds a carbon hollow-core sole with stiffness index 12 (RC810: 11), a reinforced carbon heel and a Japanese microfibre upper, and Shimano lists it at 233 g against 262 g for the RC810 (EU 43). Racers chasing every gram will notice; for most riders the RC810 gives the same fit and cleat system for less.

Do the RC910 and RC810 work with my SPD-SL pedals?

Yes. Shimano’s compatibility table lists the new SPD-SLR shoes as compatible with SPD-SL pedals and SPD-SL cleats, so you can keep your current pedals. The lower stack height is only achieved with SPD-SLR pedals and cleats, which is what Shimano recommends.

How do I position SPD-SLR cleats on the new Shimano shoes?

On the newest Shimano road shoes (such as the RC910 and RC810) you set the fore-aft position at the shoe and the lateral position at the cleat. The cleat has alignment markers and a centre window that shows the outsole grid, which makes it easy to note your position and return to it.

Carbon sole

The sole plate is made of carbon fibre rather than nylon or carbon-reinforced nylon. Carbon is stiffer and lighter, so less of your effort is lost to flex; the brand’s stiffness index is in the spec table.

Low-stack carbon sole

A carbon sole with a low stack height design that Shimano says maximises pedalling efficiency and gives a direct connection to the pedals.

SHIMANO DYNALAST 2.0

Shimano’s updated last: a wider forefoot, an optimised toe box and reduced toe spring to ease pressure on sensitive areas while keeping a locked-in feel. Made in Standard, Wide and Narrow fits.

Dual BOA Li2F dials

Two BOA Li2F dials with textile laces for fast, precise micro-adjustment and an even wrap around the foot.

Integrated heel cup stabiliser

An integrated heel cup stabiliser that helps secure the foot during hard accelerations and high-power efforts.

New cleat adjustment

On the newest Shimano road shoes the fore-aft cleat position is set at the shoe, with an extended range and easy-to-read markings, while the SPD-SLR cleat handles lateral adjustment. Splitting the two lets the cleat itself be more compact and lower.

Shimano: snug by design, so if between sizes, size up. DYNALAST 2.0 Standard has a roomier toe box than before, so riders who sized up for width may prefer half a size down. The new Wide is noticeably roomier than the previous Wide. Narrow suits riders who wore Shimano's women's models or prefer a snug, performance fit.

How to measure

Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe and measure the distance in centimetres. Measure both feet and go by the longer one.

Description

Shimano’s race-proven road shoe on the new SPD-SLR platform: a low-stack carbon sole (stiffness index 11), the DYNALAST 2.0 last with a wider forefoot, and dual BOA Li2F dials. It shares the fit and cleat system of the S-PHYRE RC910 for less money, and it still works with SPD-SL pedals if you’re not switching yet.
