Description

Quick and light, Italian-style.

The DMT Prisma Shoe 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.

This version of the Prisma's CX carbon sole has a bolt pattern 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 of the sole, it's 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, 45, 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-degrees: Maximum stiffness and responsiveness. This carbon fiber runs the length of the sole providing the stiffness overall for the entire sole.
  • 45-degrees: 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-degrees: 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 Prisma Road Shoe is available in a White/Red. It weights 250g in size 41.

  • Prisma RAM-VTR with stainless steel wire closure pulls equally across your foot, discouraging the formation of hot spots
  • Toray MR60 carbon fiber sole  has a tensile strength of 40 tons per square centimeter for maximum stiffness
  • Nine layers of carbon fiber molded at 0, 45, and 90 degree orientation offer strength and response in all directions
  • Thin soles (3.5mm at critical cleat interface) minimizes stack height for a better fit
  • Traditional three strap hook-and-loop closure let you customize your fit
  • Bonded toe and heel protectors guard against scuffs when you put your foot down at stop lights
  • Microfiber upper combines with mesh for airy weight and exceptional breathability
  • Use Speedplay’s Carbon Sole Wear Protector Shim to protect the deformation of the carbon sole
  • Speedplay’s Long Cleat Screw Kit is necessary to attach the protective shim to the bottom of your shoe

Great shoes, re-set your fit!

Awesome shoes like the above reviews.
Make sure to accurately account for the incredible lowering of (shoe)stack height if you have the Speedplay dedicated soles. Coming out of a pair of Shimano shoes I had to adjust my saddle down almost 7mm due to these shoes getting me that much closer to the pedals. The lack of the adaptor plate for 3-holes (3mm)and the stated thinness of the soles of these shoes(only 3.5mm) (while remaining very stiff) came out to 6-7mm for me. I used calipers to eyeball the thickness at first as the stated 3.5mm sole thickness was not stated when I bought mine, but I was within a mm so all good.
Therefore a significant lowering of my center of gravity that I certainly feel descending as I am a tall guy always striving to get lower.

GREAT SHOES

The DMT Prisma SpeedPlays are the first "high end" shoes I've had after wearing Specialized road shoes for the past 5 years. Up until last year I used Look Keos and bought SpeedPlays early last season. The DMTs are much more stiff and feel more secure on the pedals. After 2 rides with the DMTs, I wore the Specialized because of bad weather, and the Specialized with the adapter plates felt loose compared to the DMTs, although the direct connection cleats on the DMTs released just as easlily as the Specialized. Fit my foot well, size is same as Specialized.
