The SFI Foundation set of minimum standard specification for shifter boots used in motorsports.  Performance Analysis Shifter Boots feature a CarbonX outer-shell and an aluminized inner material.  They have flame-retardant Velcro and are double sewn with Kevlar/Stainless Steel thread.

These shifter boots were the first boots meeting SFI Specifications that feature CarbonX Shell materials.  In 2008, we introduced a new version of the Shifter boot with CarbonX Ripstop.   This material  provides for a stronger boot at a lower price.  We have common sizes in stock and can also custom make most any popular style.
