Transform your football boots with these replacement aluminium studs in silver. The set contains 8 x 11mm and 4 x 13mm soft ground studs with a practical wrench for fitting. These studs can be used as replacements on all PUMA SG football boots bought from the 2016 Spring/Summer Collection onwards. The studs can also be used as replacements on old PUMA SG football boots. However, the shape of the stud is different and may not fit the boot as per the original stud fitting.
