Product philosophy

How to define Product Performance?

Cycling shoe performance is determined by the comfort, fit, the optimal power transfer and pedalling efficiency they provide. This is achieved by us applying the right mix of materials and technologies during our in-house production process. Our product philosophy explains the decisions and trade-offs we made in order to get to our models.  

Comfort and Fit

During cycling your feet need to stay in place. You need a tight yet comfortable grip that allows your toes to move around in the toe box. The closure system is an important comfort determining factor and frankly a matter of personal taste. There are Velcros, Buckles, knobs and laces. Most important is that the closure systems apply pressure evenly across your feet. You have to decide which closure system you like best. No matter what anyone says, no one can advise you on what’s comfortable for you personally. 

Power transfer and pedalling efficiency

There are three basic materials used for cycling shoe soles: nylon, composite (which looks like carbon fibre, but really isn’t) and carbon fibre. Put simply, the stiffer the sole the better the power transfer and the higher your pedalling efficiency will be. There is a massive performance difference between carbon fibre and the other materials in terms of stiffness to weight. Some consider ultra-stiff soles to be uncomfortable. We obviously cannot disagree with personal taste, but from a performance point of view a stiff sole is preferred. 

At nimbl we only apply carbon fibre in manufacturing our chassis as we believe the material offers the performance in stiffness to weight that fits our brand. There are many sorts of carbon, there are even more (brand specific) marketing terms amongst our competitors. We simply cannot and will not put a marketing label or other fluff on our sole systems. Trust us, they are the best money can buy, even without a stiffness index or a funky name. 


Making a light shoe is in itself not complex, but to make a light and stiff shoe is more of a challenge. Lightweight is something we strive for here at nimbl, in fact we are quite good at that, but it is not a goal in itself. When weight becomes the primary target, it inevitably leads to concessions in the other performance areas such as durability or power transfer. Though our shoes are amongst the lightest in the market, we hold the belief that 10-20 grams more for a stiffer, more efficient pair of shoes are grams well spent.


Hot and sweaty feet are uncomfortable, whether you are going at race or touring pace. Cycling shoes have synthetic or leather uppers, and often have several mesh panels to keep your feet ventilated. The amount of ventilation you require is dependent on your climate. A shoe for the south of Spain obviously requires a different level of ventilation than a shoe being ridden in Northern Europe.
