Suplest Streetracing Carbon road shoe



Comfortable, stiff-soled, secure road shoes although lacking exceptional features you might expect at this price

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.

These Suplest Streetracing Carbon road shoes put in a strong all-round performance although they lack the standout features of some other options at this price.

You might not know much about Suplest. The Swiss brand has only been around since 2007 and they've fairly recently got distribution through the Evans chain in the UK.

This is the top-end road shoe which is available with a ratchet upper closure (like wot we have) or for £179.99 with three Velcro straps – so you're paying an extra £45 for the ratchet version.

The uppers are distinctive. I'm used to looking down and seeing skinny, minimalist shoes. Well, as skinny and minimalist as size 46s ever get. These are noticeably more roomy than most across the forefoot. The toe box is high and the section right over the tips of your toes is rigid thanks to some clever materials jiggery pokery.

The uppers are made from 'organic grid' which is a tough microfibre material, the thickness varying around your foot. Suplest say the thicker areas offer higher reinforcement and the thinner areas increase comfort although you'd be hard-pressed to tell the difference in use.


Ventilation is provided by perforations in the forefoot and the padded tongue. I didn't find my feet stayed as cool as in shoes with large mesh panels but I'm not particularly bothered by that. If you do tend to get uncomfortably hot feet, maybe that'll be more of an issue for you.

The whole of the upper from the buckle forward is one piece so there are no seams to bother you, and padding around the heel keeps things comfy back there. The heel cup is quite narrow, especially compared to the fit up front, and I found that it held my foot securely in place without any unwanted lift.

The ratchet closure is pretty chunky so it's easy to tighten from the saddle although the button to loosen the strap is small and requires quite a lot of pressure compared to others I've used.


The outsole is carbon fibre with graphics to match the uppers. We always comment on sole stiffness in shoe reviews but it seems that there's rarely any point these days. The Suplest's soles, like those of all the other high-end models we've tested lately, are absolutely rigid; there's no flex whatsoever in any direction as far as we can discern.

Two vents, one under the toes and the other under the midfoot, provide some airing while heel and toe grippers – along with your cleat once you've bolted it in place – provide some protection for the sole and do a good job of stopping you slipping on wet Tarmac. The rear one is replaceable, which is a thoughtful feature to improve longevity. The sole is drilled for three-bolt cleats (there's no Speedplay-specific version) and a textured finish around the holes helps hold your cleat in place.

The EVA insoles are neat too. They're a little thicker and a touch more spongy than most – not much, but just a bit – and I found them really comfortable.

So, comfortable, stiff-soled and secure, these are good shoes. It's just that if I'm spending £225, I want shoes that are exceptional in some way – mega-light, super-supportive, mouldable for the ultimate in comfort... or whatever. There's no standout feature here. That said, they're strong across the board so they're still worth considering, particularly if you're after a bit of extra space in the forefoot.

Make and model: Suplest Streetracing Carbon road shoe

Size tested: Size 46, Red/White

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Here's the write up: "The Suplest Supzero Streetracing (Buckle) 2012 Road Shoe is Suplest's top-of-the-line shoe for road racers. From the carbon sole to its seamlessly manufactured upper, this model is tailored to performance.

Tell us some more about the technical aspects of the product?

Suplest says this about the upper, "Suplest uses a special micro fiber, which is called 'Organic Grid Micro Fiber', a light and comfortable material. This allows us to cleverly select areas that need a higher reinforcement to keep the foot stable, while other areas are thinner to increase overall comfort. The forefoot area is seamless to eliminate any unnecessary pressure zones."

And this about the sole: "The light carbon sole is an important part of the Ergo 360° concept. It has been engineered for performance cyclists who want a stiff sole without compromises. Our Ergo 360° concept guarantees maximum comfort and efficient power transfer. The sole has two air vents, offering airflow from underneath. For safe walking suplest added rubber inserts in the toe and heel area. The heel tread is replaceable."

Rate the product for quality of construction:

Well put together - no worries on that front. The microfibre upper is reasonably tough and you can wipe it clean easily.

Rate the product for performance:
Rate the product for durability:
Rate the product for weight, if applicable:

These are reasonably light but certainly not exceptionally light. The Giro Factors we reviewed in a size 45 were 510g the pair. These are 1 size larger and 200g heavier.

Rate the product for comfort, if applicable:

Comfy with plenty of space across the toe area, but you can get mouldable insoles and uppers on shoes at this price.

Rate the product for value:

Tell us how the product performed overall when used for its designed purpose

Solid all-round performance... just not mind-blowing for the price.

Tell us what you particularly liked about the product

The super-stiff carbon soles.

Tell us what you particularly disliked about the product

The button to loosen the ratchet is really small and requires a lot of pressure from your finger.

Did you enjoy using the product? Yes.

Would you consider buying the product? I'd probably go for something mouldable at this price.

Would you recommend the product to a friend? If they needed room across the forefoot.

Does anyone know where to get the replaceable heel treads from? I'm loving the shoes but struggling to find replacement inserts.

I've just started using the equivalent MTB shoes from Suplest. Not bad so far. Bit "football boot". Quality good, heel a bit loose. Jury out. They look SPANKING though.

Got a pair of these about 2 months back. always have used specialized because of wide toes. Found these great. roomy up front - no slip at heel. Cool in the heat.I had a pair of Giro Top shoe (prolight) and my feet would overheat instantly - hardly any ventilation.
I am always trying to find rigid shoe nirvana - tried all the top end shoes and these are th most comfy for my feet.
But, cycling shoes are very much a "horses for course" thing.
