OCsystem® Spare Parts

The cleat type is determined by your boot brand, model, and size. We have made it simple to quickly identify the correct OC fitting with a dedicated guidance page: https://icegripper.co.uk/pages/icegripper-ocsystem-reference-page-check-your-footwear-model If you're unsure, simply contact us using the CHAT button, found bottome right on every web page.

It depends on the part. WB1, WB2, and WB3 full sets contain 4 pieces and replace all cleats on the heel and forefoot of a pair of boots (both feet). The KB2 set contains 2 pieces and covers one boot only — so if you need both boots replaced, you'll need to order two KB2 sets.The product description clearly states whether it is a FULL SET replacing all parts on a pair of boots or is just a SINGLE replacement set.

Not necessarily. From 2024 onwards, Mammal began transitioning to YB1 (men's) and YB2 (women's) fittings across many of their boot models. WB1 and WB2 were used in first-generation Mammal boots. Before ordering, we strongly recommend measuring your existing cleats and comparing them against the dimension images in the product listing to confirm compatibility.

There is no difference in size, dimensions, or performance between Green and Red OCsystem cleats — the colour is purely cosmetic. Green is an older colour that is being phased out and replaced with Red as the standard. Both variants use the same TPU body and heat-treated steel spikes, so either will fit and perform identically.

OCsystem cleats are made from TPU with heat-treated steel spikes and are built for multiple seasons of use. You should consider replacing them when the steel spike tips become visibly blunt or worn flat, when the TPU body shows cracking or deformation, or if a cleat no longer clicks securely into the boot sole. Regular inspection at the start of each winter season is recommended.
