To find your current size, check the top panel of your AIR KICKS® product box to see if yours are Small, Medium or Large. Your box also indicates the type of T-Springs (either T-0, T-2, or S-3) which came installed in your boots at purchase.   As your body weight changes, you can customize your AIR KICKS by interchanging your current T-Springs for a different pair designed for either LESS or MORE weight (shown in the chart).  The weight/size chart shows ALL the different AIR KICKS® sizes and interchangeable T-Springs available. Order Replacement T-Springs for the Air Kicks boots you own directly from this page by choosing the size which is right for you. 

When you receive a new pair of T-Springs, you will be able to install them yourself (instructions will be included).

Please Note: Springs named with a "T" at the beginning (T-0, T-1, T-2, and T-3) can be used for size SMALL and MEDIUM Air Kicks boots only (#11205 and 11206). Springs with an "S" at the beginning of the model name (S-2, S-3, and S-4) can be used for size LARGE boots only (#11207).
