If the ground is wet and slippery you can get better grip with mixed and stud shoes because studs pierce deeply into the ground and give added support.

The GRPS system offers you greatest stability because of its improved design and makes your running easier because of better pressure absorption.

Football shoes have different kinds of threads. For example, if you wear Adidas shoes you need another system than using Nike shoes. So, GRPS are compatible with all conventional brands. Note: Check out if you need to buy GRPS Type X or Y!

GRPS Type X and Y have different kind of threads, compounds and heights. If you need GRPS Type X or Y depends on to the brand of shoes (thread) that you are using.

The GRPS System consists of several parts to adjust different heights and combinations easily. You may need different variations for different conditions.

GRPS Type X consists of body (10mm/8mm) and bolt (5mm/3mm) which you can combine for different heights. Here you can find all parts of GRPS Type X.

GRPS Type Y consists of body (8mm), bolt (3mm) and an optional ring (2mm) that you can use for different heights. Here you can find all parts of GRPS Type Y.

GRPS are quite resistant and made for using them several seasons. In case of attrition you can easily replace its bolt and use GPRS even longer.

The ideal amount of force required is 4Nm. We recommend tightening each bolt until you notice clear resistance and the bolt has reached its end of turn.

Note: Fix all bolts tightly and carefully. If you fix the bolt too less, it might loosen later. And if you fix it too much, the thread may get damaged.

GRPS can be fixed easily.

1. Remove your old cleats.
2. Choose your favourite GRPS combination and tighten the bolts manually.
3. Use the hex-wrench that you can find in your GRPS box to tighten all bolts strongly and carefully (4Nm).

In the video you can find more information for assembling your GRPS.

No. If you have installed GRPS properly (4Nm) you do not need to retighten them.

Note: Check all bolts after using them the first time.

Use the sharp end of the hex-wrench to remove all kinds of dirt.

Note: Be careful while using the hex-wrench to avoid any injuries.
