Cleats is a passive skill in the Wind Master skill tree which increases your shaman's friction by 20% for each skill point allocated.
The maximum allocated skill points is 5, which, when fully upgraded, increases your shaman's friction by a total of 100%.
When 5 skill points are allocated in this skill, every ground will be like chocolate for your shaman.
It is recommended to not allocate more than one skill point into this skill unless you are inexperienced at wall jumping. One skill point is usually enough to stop the shaman from being blown away in wind maps.
