M1K replacement mouse feet
The stock mouse feet of the M1K were Hyperglides. Hyperglide has been engineering mouse feet since 2004. Hyperglides of course are famous for their rounded edges, which ensure scratch free gliding over your mousepad.
Hyperglides are made from Polytetrafluoroethylene (PTFE), which prevents the annoying stick-slip effect due to very low coefficients for both static and dynamic friction. The particular Hyperglides we use for the M1K are 7 millimeters in diameter and 0.65 millimeters thick. All four Hyperglides together weigh in at just 0.21 grams.
