The 13mm profiler is specifically designed for playing on slippery surfaces. It offers you maximum stability and high flight performance. We recommend it for the 3rd line, but also for goalkeepers, so your stopped starts won't have the same feel! This package is only for Adidas 6-stud shoes (excluding Kaiser and old generation Copa). Package contents (Football/Rugby): - 12 Adidas screws with a 13mm thread - 20 adjustment washers - 13mm adjustment key - 1 paper note.
