Insert Systems

What Are Insert Systems?

Insert Systems refers to the type of receptacle found on the bottom of your golf shoe. The Insert System determines the type of spike that will fit your shoe. Different manufacturers use different types of receptacles, so it's important to be able to match the right spike to the right Insert System.

Currently, there are at least 9 different branded receptacles on the market, with several being cross- or backward-compatible. The guide below shows the 5 most prevalent insert systems and the difference between each. Once you've identified the type of receptacle on your shoe, use our Spike Replacement Guide to find the spikes that you need.
