DMT Radial Speedplay Shoes

Product Description

Speedplay is our best-selling brand of pedals by a ratio of 3:1. And that's 3:1 over all other pedal brands combined. With that thought in mind, we're excited about this Speedplay-specific version of the DMT Radial Shoe. The Radial is DMT's top of the line shoe for riders who eschew mechanical buckles, and this version of the Radial's CX carbon sole is specific to Speedplay cleats. That means no more 3-bolt to 4-bolt adapters! This lowers your stack height and gets your feet closer to the pedal spindle -- giving you better pedaling efficiency and a lower likelihood for hot spots. Please Note: When mounting Speedplay cleats directly on these shoes it is imperative to use Speedplay?s Carbon Sole Wear Protector Shim. Failure to do so may damage the sole and will void the warranty. We also recommend using Speedplay's Long Cleat Screw Kit to ensure that your thread interface is sufficient to keep the cleats attached to the shoes during hard efforts.Like the Look version, the Radial 's CX carbon sole is made from Toray MR60, which is a 40 Ton high modulus carbon fiber. That means it has a tensile strength of 40 tons per square cm. In other words, it's got stiffness in spades. Toray is one of the top manufacturers of carbon fiber world-wide -- it's the same stuff used by Pinarello in the Prince Carbon and Montello FP8. The lay-up of the carbon and the shape of the sole are exclusive to DMT. The soles are made from 9 layers of carbon fiber molded at 0-degree, 45-degree, and 90-degree angles. Of course the sole must be looked at as a whole, but each angle in the carbon lay-up will offer strength in different ways:0-degree: Maximum stiffness and responsiveness. This carbon fiber runs the length of the sole providing the stiffness overall for the entire sole. 45-degree: Torsional rigidity allowing a responsive and firm steering feel. It provides stiffness to prevent twisting of the sole due to pronation or supination. During the typical pedal stroke your foot will exert different forces at different vector angles to the sole. Without the torsional rigidity afforded by this layer, the sole would be able to twist along its axis leading to a loss of efficiency. 90-degree: Strength and durability for long life and consistent high performance. This layer of carbon fiber helps strengthen the overall form of the sole. Without it the sole wouldn't have the strength to withstand lateral forces. It also helps in increasing the torsional rigidity.Another area where these soles excel is in their thickness - or in this case thinness. Keeping the distance between the bottom of the foot and the pedal interface as thin as possible increases the maximum transfer of power to the pedals through more of the stroke. The DMT CX carbon sole uses varying thicknesses in different places. But at the critical cleat interface it is a wispy-thin 3.5 mm allowing for an optimum foot to pedal distance. The DMT Radial Shoe keeps the uppers wonderfully light and fairly traditi

Strengths:    Stiff, light, and comfortable. Great looking too.

Weaknesses:    Need SpeedPlay plates to protect the sole which is an extra $12+S&H.

Bottom Line:   
I was lucky enough to get a pair of these on sale compared to the $265 sticker price. Going from 5yr old Sidi Genius 5 to these was a big step. They recommend getting the speed play plates to protect the sole, and also go a 1/2 size bigger if your foot is wide. I did both. Now I know how it feels to have a pro level shoe and why. They are super stiff, light, and also comfortable. I can actually feel all the power going to the pedals with each stroke, I'm not sure if it's because my shoe being closer to the pedal (no more adapters with these) or it's because the shoe is much stiffer and lighter? They are very breathable so make sure to use shoe covers in the winter.
