Starlit is composed of 6 layers and different materials.
Starting from the top to the bottom:
Uppers are realized with the finest materials, following both trends and technical requirements. To ensure the maximum comfort all uppers are adjustable both with laces or velcros or buckles.
Moreover the internal lining is Coolmax®, that is a well known high tech fabric, made from specially combined polyester fibres, specifically engineered to keep users dry, cool and comfortable.
• Insole and Shanks
Two parallel steel shanks are found within the insole. The shanks are placed on the insole lateral edges of the shoe to provide sagittal plane stiffness, extra support and torsion stability which is a must for this kind of shoe.
Usually in "normal" shoes there is only one shank. Starlit has been equipped with 2 shanks, that are parallel to better ensure stability and a perfect distribution of the body’s weight along the whole shoe.
The insole helps the foot support itself in all the right places thanks to the ergonomic Scholl’s New Exercise anatomy of the footbed
• Exhaust valve
In the centre of the superior midsole there is a valve which characteristic is to allow the air to exit but not enter. Both footbed and insole have holes that are connected with the valve through ducts. The air enters through the upper and the lateral breath highlights and is pumped out through the valve. This ensures air circulation and cooling effect.
• Lower and upper midsole
Lower and upper midsole are both made from PU (Polyurethane), but the two layers of the sole are of different hardness to grant both cushioning and roll out support.
The two layers of the midsole are connected through projections that form suspension pyramids and all these parts work jointly thanks to their different density.
The lower midsole provides firmness to the whole sole and a stable support for the softer upper. The upper midsole cushions the foot and gives more shock absorption.
On the medial side (the internal part of the foot) the projections using stiffer material are 60% of the height and those with softer material are 40% of the height so to offer resistance to overpronation (the common tendency to roll the foot inwards while walking).
The lower midsole extends into the forepart to provide extra resistance effect and rocker effect (the propulsive action).
Under the impact point, there is a deeper layer of highly compliant material, so to offer extra shock absorption at heel strike.
The outsole is made from durable rubber materials to ensure good grip.
In particular, the outsole construction has been tested by SATRA, one of the best footwear laboratories in the world, for slip resistance properties. Starlit has passed the internationally recognized standard test TM 144 which means the shoes offer enough resistance to slip both on dry and wet tiles.
