PLUG RACE liners are designed to work in tight fitting, low volume race shells. These liners provide a high performance fit, with a lace up tongue and stiff injection shin and cuff reinforcements. Featuring a 2mm Strobel sole with removable 7mm foam insoles for maximum volume adjustment underfoot.
The Plug Race is a low volume liner and works best with a shell fit* of One finger (1/2”) or less
If your shell is a half size, round down for this model.
For best results we recommend having these liners heat molded at a shop by a professional bootfitter. Stiffer models require more attention when heated, while others can be easily molded by using the home fit kit.
*Checking Shell Fit
In order to determine the right thickness of liner for you, start by checking your shell fit. To do this, pull the existing liner out of the shell. Stand with your bare foot inside the bare shell, and move your foot all the way forward so that your toes are touching the end. Bend your knee and flex forward a bit so that you can slide your hand or even a pencil into the shell behind your leg. How many fingers can you fit between your heel and the shell?
