The Shimano RC703 street biking sneakers are designed for these searching for a stage of efficiency just like the range-topping S-Phyre mannequin however with out the value tag. Think about these sneakers the second tier, or the Ultegra stage in Shimano’s street biking shoe lineup.
Being a part of such a lineage means these sneakers are meant for eager amateurs in search of fast-ride efficiency. Throughout my time testing these sneakers, they’ve carried out properly. There have been a couple of niggles, which I’ll get onto later however as second-tier merchandise go, these sneakers are a worthwhile addition to Shimano’s lineup and supply a powerful selection for riders in search of one of many greatest biking sneakers at a cheaper price.
The development
The shoe is constructed with a ‘excessive rigidity, hole carbon midsole’ mated to an artificial leather-based higher, with two BOA L6Z dials because the fastening system of selection.
The higher materials partially wraps across the carbon sole which Shimano claims ‘reduces overlap and supplies a glove-like match’. I can’t say I totally agree with this assertion. Whereas the sneakers are comfy, they’re nonetheless sneakers designed to ship for these searching for efficiency. To me, ‘glove-like match’ suggests a tender, comfy, supple match, whereas I discovered these sneakers provide a agency, sturdy, locked-in really feel. What the wrap-around higher does present, is a sleek-looking shoe because it cloaks the carbon sole and creates the phantasm that almost all of the shoe is one uniform color, very like the range-topping S-Phyre mannequin.

The insoles provide little arch help and are fairly flimsy. I might advocate shopping for an aftermarket insole that provides a bit of extra help and is tailor-made to your ft.
On the surface of the sneakers, the toe field space performs host to a small plastic bash guard, which takes the brunt of tyre scrapes when clipped in, and any bumps which end result from strolling round. I like this function loads and it’s one thing you may see on different common street biking sneakers. It protects the fabric from being minimize up by abrasive surfaces and makes cleansing tyre scrapes a lot simpler.

The BOA dials are no-nonsense; merely twist clockwise to tighten and pull out to launch the stress. BOA dials are near being an business normal for biking sneakers and work properly for many who favour on-the-fly adjustment. Except for the mechanics of the closure system, I do like how the shoe includes a tongue that sits in your foot after which a cushioned strap is pulled excessive of the tongue by the BOA, which means stress distribution is stored good and even.
The trip
I first used these sneakers when coaching indoors. I discover this a pleasant technique to test I’m pleased with the cleat place and get used to how they really feel in a extra managed setting. The very first thing I seen was how stiff the soles had been. Rated as a ‘10’ on Shimano’s stiffness chart, the RC703s are solely bested by the range-topping S-Phyres at ‘12’, and it left me wanting for little or no. I felt related to the bike in a non-squishy or flimsy means. I used to be locked and able to go.

After my preliminary indoor rides, the sneakers joined me on a visit to Spain for additional testing. One small situation prevailed after my first couple of rides – a pinch level on the higher proper facet of my left foot. The sting of the tongue was pushing into my foot and making a good bit of ache, which led to me loosening the shoe to alleviate the problem.

The discomfort continued till I used the sneakers to the purpose the place the uppers softened and have become extra malleable, higher accommodating my foot. My ft might have swollen within the warmth additional contributing to the problem; now I’m again within the chilly UK, both the sneakers have worn in or my ft are now not a bit of bloated. The actual fact is, no matter has stopped the problem, the sneakers now match significantly better than they did initially and are now not inflicting me any ache.
Worth and conclusions
The Shimano RC703’s value £220, or $250. The simple comparability to make is towards the vary toppers, which is the place Shimano claims the trickle-down tech these sneakers profit from originates. The RC903s value £349 or $450, which is a giant leap in value. The RC903s are lighter, function higher air flow, provide extra stiffness and are shod with fancier BOA dials, however the price to get there may be vital.
In case you are in search of a pair of sneakers that carry out at a stage that’s nearly incomprehensibly near the RC903’s, then these received’t disappoint. The vary of sizes obtainable in each normal and huge matches is complete and the comparative worth is tough to disregard.
In fact, be sure you put on them in, as a result of they get higher the extra you employ them. I might additionally counsel getting some insoles that present the right amount of arch help too. Lastly if you happen to, like me, love a white pair of sneakers, then choose your driving days fastidiously based mostly on the newest climate forecast.
