At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Bontrager Circuit Road Cycling Shoes are comfortable and well constructed, and suitable for most types of sporty riding. They're compatible with both two- and three-bolt cleats and offer a relatively wide fit that will be ideal for some.

This latest version of the Circuit is billed as being 'the perfect choice for riders who want to tackle a variety of road rides without making their feet pay for it'. It's an everyday road riding shoe, in short. This means it seeks to strike a balance between comfort and performance. I'd say it's largely successful in that.

Just as with previous incarnations, the Circuit is secured with a Boa dial and a Velcro strap. Higher-end shoes often feature a couple of Boa dials, but this one-dial arrangement still offers a neat and secure fit. I found that one foot did get a bit tingly on one ride, but this was really just from over-tightening and so easily resolved.

A minor frustration is that the dials only adjust one way. There's no ratchet micro-release. If you need to loosen a smidge, you'll have to release the dial and then retighten.

The Circuit's updated upper is constructed from synthetic mesh and TPU with perforations to provide breathability. This proved comfortable over a five-hour ride, with a split tongue to dissipate pressure at the ankle also a welcome touch.

In terms of breathability, there are visibly lighter, airier summer shoes out there, but with a mesh window under the toe box as well, things didn't feel too steamy even when temperatures were pushing 30 degrees.

The shoe's 'Bronze Series' sole is 67% nylon and 20% glass fibre, with carbon fibre, TPU and metal rounding out the mix. The end result is something Bontrager says offers a stiffness of 7 out of 14 on its index. I don't know what the two ends of that scale represent exactly, but the shoes felt decently solid to me when I was putting my weight through them on steep climbs. You can find stiffer soles, but these aren't really being sold as all-out race shoes. I'd have liked more pronounced arch support, but this is an individual thing.

Significantly, the shoes are suitable for both two and three-bolt cleat systems, which will be good news to road cycling fans of the SPD system. The necessary two-bolt mounting plate is, however, sold separately.

In terms of fit, the 43 I tested was broadly equivalent in size to other cycling shoes I've worn. Broadly is the word, though, because Bontrager says the Circuit is designed to offer 'a slightly roomier, high-performance fit'. With my relatively wide feet, I was very happy with this. Others may not be.

Appearance-wise, the Nautical Navy/Radioactive Coral shoes on test provide a bit of a challenge if you're fussy about maintaining a coherent colour scheme in your attire. I neatly sidestepped this sartorial landmine with my tactic of giving up and not caring – but you could instead go for one of the other options, like 'Black' or 'White', say. 'Radioactive Red' and 'Radioactive Yellow' are also available. (It's not clear what precipitated all this radioactivity.)

The price of the Bontrager Circuit Road Cycling Shoes has climbed a little since we last reviewed them, but looking at some of the competition, they measure up fairly well.

Shimano's XC5 (XC501) SPD Shoes are arguably the standouts in this price bracket (okay, a tenner more). You could employ them for the same kind of sporty endurance riding for which the Bontragers are intended, but they aren't quite the same in that they're SPD-only shoes, with recessed cleats.

Decathlon's Van Rysel RR 900 Carbon Road Cycling Shoes, meanwhile, offer a more race-centric option with a carbon fibre sole for the same price.

Both of these feature a Boa dial, unlike many of the cheaper options, such as the Giro Techne shoes (£89.99) or the Bont Riot Buckles (£99).

At £99.99, the Specialized Torch 1.0 Road Shoes are a more affordable option with a Boa dial closure – but then, as with the Giros and the Bonts, they don't cater for SPDs.


Overall, the Bontrager Circuits have proven comfortable for long rides, fast rides, and leisurely rides, and seem hard to beat at this price point in terms of features and construction.
