What is the difference between the Hotronic Universal S4+ Foot Warmer and the Hotronic Custom S4+ Foot Warmer?

The Custom kit is designed to be used with boots that have a custom-fitted insole already installed. The Universal kit is for boots that still have their stock insole, and includes a Heat Ready insole to replace the stock one.
