In order to reach the highest level of SRC (slip resistance), Jolly developed for its Fire and S&R collections a new outsole, shaped on the new J-Morphic last The outline of our new J-Morphic last, much more “rounded”, wants to be a valid alternative to traditional “flat” outsole/last systems that use metallic antiperforation insoles.
The advantages are:
- the profile is more modern, with a wider toe box so that your toes are not cramped together.
- the rounded heel eases the footing during the roll-over phase, avoiding a sharp edge annoyance; it also ensures higher levels of slip resistance.
- a better feet roll-over motion that allows the shoes to perform the 90% of each step without bending the outsole, the creasing stress on its bonding and preventing upper’s wrinkles that can cause pressure points on the foot. The walk will be more comfortable, the foot less stressed and the muscles more relaxed.
- the energy absorption level is given by the rubber compound of the outsole, by the height and shape of its cleats and inner net, by the composite material of the antiperforation insole, and most of all by our J-Morphic last: so that, in order to give our excellence lightness and energy absorption results, Jolly shoes don’t need PU hidden midsoles or inserts that can melt at 130° and make the boot collapse internally.
