Air Kicks Anti-Gravity Running Boots, Medium (T-2) for 99-176 Lbs

The brand NEW, improved wider boot design of the New 2011 AIR KICKS Range has a more ergonomic shape, so just three sizes (Small, Medium, Large) will fit virtually any foot, from 8-year olds to adult --- male or female. That means it is easier to determine your size. The new design retains the patented JUMPING JAX technology, which utilizes heavy-duty, rubber T-Springs to capture and then transform downward energy into longer, low-impact strides that are gentle on the ankles, knees and back.

Not only do AIR KICKS Anti-Gravity Boots deliver a soft cushiony motion that's gentle on joints and bones, they also provide a sensational calorie-burning, coordination-building, leg-strengthening workout. They feature high-traction non-marking treads that are safe to use on virtually any surface, indoors or out, and won't mar floors!

Item #11205 Size MEDIUM (T2 Springs for 99-176 lbs.) replaces the older (now discontinued) model #11203 AIR KICKS SR. They will fit over the user's athletic shoes, and are adjustable to easily accommodate most shoe sizes for users in the weight range, including the following: YOUTH sizes 4 to 7, WOMEN sizes 5.5 to 11.5, and MEN sizes 6 to 10.

Following are the additional sizes of the New AIR KICKS models:
€ Size SMALL (#11206) for users 55-99 lbs (with T0 T-Springs)
€ Size LARGE (#11207) for users 121-199 lbs (with S3 T-Springs).

Another improvement to the new 2011 AIR KICKS models is an extended range of Interchangeable Replacement T-Springs, which can be interchanged on any of the New AIR KICKS boots to adjust the user body weight range without the need to buy a new pair of AIR KICKS!
