DMT Prisma Shoe - Men's - 2010 BCS
The Prisma Road Shoe is DMT's latest salvo fired in the direction of their Italian cousins Sidi and Diadora. Though the brand DMT is a relative newcomer to being visible in the professional ranks, 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. The Prisma road shoe takes everything DMT knows about shoe fit and unites it with their extensive research into producing uppers that fit like socks, which they top off with an amazing carbon fiber sole exclusive to DMT.
The Prisma makes use of a stainless steel cable closure system that molds the upper to your foot. Since the cable pulls through the entire closure system it will conform equally well to your forefoot as to the mid-foot. Unlike other mechanical buckles, the pressure won't be isolated to the area directly beneath the buckle. The Prisma's RAM-VTR system uses a lever to take up the line as opposed to dials which are usually used. This makes adjustment easier and quicker while allowing greater adjustability for fitting.
The Prisma'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 DMT Prisma Road Shoe is available in White/silver. It weighs 250g in size 41.
- Carbon fiber sole features nine layers, woven at 0, 45 and 90 degree orientations for unmatched stiffness throughout the sole
- RAM-VTR (Rotary Activated Monofilament – Variable Tension Regulator) provides ergonomic cinching levers for exact fit
- Bayonet-style joint allows for easy RAM replacement
- Microfiber upper combines with mesh for airy weight and exceptional breathability
- Entirely Italian design adds aesthetic appeal
Bottom Line:
You don’t have to have Italian shoes to ride faster, but it helps.
