Everything you need with a little extra style thrown in.
Most of us are used to the idea of pros using custom frame builders and then sticking the bike sponsor's name on the down tube. Who really thought Jan Ullrich was time trialling on a Giant? And we all loved 7-Eleven's non-Huffy Huffys in the '80s. Gerolsteiner and T-Mobile maybe single-handedly kept Andy Walser living large for the last decade. But it may occur to us less often that when a rider has on a pair of Diadoras, those aren't really Diadoras. Though the brand DMT is a relative newcomer to being visible in the pro peloton, the company has decades of experience manufacturing custom made shoes for some of the top names in the sport. Having long acted as a custom shoe maker means that DMT has an enormous backlog of shoe lasts. This historical data has allowed the designers to incorporate a huge catalogue of foot quirks into their stock shoes.
Enter the DMT Radial -- the top of the line DMT model for riders who eschew mechanical buckles. 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 woven at 0°, 45° and 90° 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. The layers from the inside out are as follows: 0, 45, 45, 90, 0, 45, 0, 0, 45, UD Woven Exterior. Each degree provides different features:
0°: Maximum stiffness and responsiveness. This carbon fiber runs the length of the sole providing the stiffness overall for the entire sole.
45°: Torsional rigidity allowing an 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°: 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. The sole functions as a unit but each layer contributes to the overall rigidity of the whole. Without all layers working together the sole would be in danger of twisting slightly, which would rob you of efficiency and power in your pedal stroke.
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 Radial keeps the uppers wonderfully light and fairly traditional with a three strap system. The upper's microfiber combined with the soft mesh guarantees a comfy fit with a maximum amount of circulation. The bonded toe and heel protectors guard against those nasty scuffs that can result from a bit of clopping around the coffee shop parking lot. The Radial Shoe is available in Silver/black and White/silver and weighs 255g in size 41.

Awesome Shoe - light, stiff and flashy
- Familiarity: I've put it through the wringer
Great road shoe, the carbon sole is really stiff and the velcro straps give you infinite adjustability. My only complaint is that the shoe fits a little short/tight in the toe. 1 size larger might be perfect. I've had hot spots on really long rides (>200KMS) but otherwise these shoes are perfect
So pimp, so light
Awesome shoe...but sadly, a bit narrow at the toe.
I normally wear a 9.5 street shoe, with a wide forefoot. I had heard that DMT run wide, so I figured I'd be safe with a 43.5. Unfortunately, while the overall fit was good, the tapering at the toe box was such that my big toe was squished just enough to make it a non-starter. I wish these would have worked, the gloss white looked killer, and they weighed next to nothing (especially compared to my 15 year old boat anchor sidis).
I have had these for about 8 months now. I have them in white, wish I could justify buying a pair in silver as well.
I weigh 165 (as a reference). I currently have plain sole inserts, not carbon. The boot is very comfortable in all conditions. It gets very hot here and these ventilate very well, in the winter I wear a booty. For my style of riding (mostly rolling hills and distances between 30-85 miles) the stiffness is very comfortable while still transferring most of my power to the crank. I have a narrow foot and they fit well without any rubbing or discomfort in my heel.
I believe that what you buy for your foot is the most important purchasing decision. With that said, I will be buying these again!
is this the Look sole or the Speedplay...
