Crono CR1 Carbon Road Shoes

Short version – the Crono CR1 Carbon Road Shoes are by far the most comfortable disco slippers I've ever worn. They're also light, stiff and very easy to get on and off, thanks to twin Boa dials that also make accurate tensioning a breeze. They even look brilliant, if you ask me. They're up there with the best road cycling shoes you can get.

The CR1 sits at the top of Crono's range, and the company rates the sole a 10 for stiffness. Despite the rigidity – thanks to great shaping and the plush but supportive insole – they really are extremely comfortable from the second you put them on. I never felt they were spanking my soles on bad roads, or inflexibly letting my heels lift.

The sole is full carbon (so no glass fibre mixed in), and beautifully shaped for obvious mechanical stiffness under your arches; it has two distinct beams here, and flattens off towards the toe.

Up front there's non-replaceable toe bumper and a small vent, and just behind the cleat there's another small vent. You can see just how thick the six-layer carbon is through these – it's a substantial 2mm.

These vents, along with the laser-cut holes in the sides, give a reasonable amount of airflow, if not masses. While the test period was cool to mild rather than baking, the various holes let in neither enough spray nor cold air to cause comfort issues with any great rapidity. I'd say they'd be fine, if not super-breezy, on hot summer days.

Inside, the footbed is not just flat. There's some arch support (presumably not that much – I have very flat feet but these don't dig in) and an overall mix of curves that really are extremely welcoming if you're a foot. Possibly this is part of the 'SAS' shock absorption system... Crono doesn't actually say what that is. But these are good at damping out vibes. On rough tarmac, there was noticeably more buzz coming through the saddle and bar than through the CR1s.

> How to choose the best cycling shoes for you

There's no traditional tongue in these. Instead, one side wraps over your foot and the other wraps over that, and the resulting toe-burrito is both very easy to get in or out of (unlike some shoes, or indeed some burritos) and very easy to adjust. The front Li2 dial does the whole forefoot, and the top one does the broad closure. Both dials micro-adjust a click at a time in either direction, or pull up to completely release.

While the foothole – hang on, I should make sure that's the official technical term... yes, that checks out – while the foothole looks pretty big, once tightened these prove very secure. The heel has a nice deep cup to it, and the 'anti-slip' lining manages to be rough to the touch yet soft at the same time; it works really well.

Be aware that Crono has gone rogue and makes these shoes the size they should be according to the number on them. Weird, huh? Given that road shoe sizes are typically as random as lottery numbers, that's a surprise. I almost always need to wear a size larger than my 'street' shoes, and ended up having to swap the test pair for a replacement in my actual size (the weight given is for the size 45s).

Value

At £223.20 (that's a permanent discount by the sole UK importer, Merlin Cycles, so we're taking it as the effective rrp) these are hardly cheap, but you can pay considerably more for much the same thing. The Specialized S-Works Torch road shoes are £385 and only 87g lighter, even in the scale-model-like size 7 Liam tested. Also, they don't even have pull-to-release dials. On the other hand, the dials are metal and do look like they're off a 1970s TV set, so there's that.

The Fizik Tempo Decos Carbon Wides Matt tested (read his review here) are lighter at 446g (albeit in a similarly childlike size 7), but the insole is basic, adjustment is limited and the price is higher. They're £274.99.

The Udog Cima Pure Blacks are a very close competitor, though, at £220 and 586g. They have knitted uppers, too, if you prefer that.

Conclusion

As I said, these are the most comfortable road shoes I've ever worn, but at the same time they're very stiff for excellent efficiency and very easy to slip in and out of – nobody likes to faff around getting shoes on and off, after all. These, in a nutshell, are great.

Verdict

Extremely comfortable yet very stiff road shoes – these are lovely
