Normally you can use iWALK3.0 with a cast or boot without any problems. But in some situations with boots that are high on your shin, you can develop a painful “hot spot” at the upper edge of the boot or cast. We’re going to show you why this happens, and how to easily fix it.
Figure 1 shows where a painful hot spot can occur with some boots or casts.
Without a cast or boot, the front of your shin contacts the knee platform uniformly as shown by the dotted line above.
Some boots or casts cause the shin above the boot or cast to be elevated so it doesn’t contact the Knee Platform. This concentrates most of your weight to the upper edge of the boot, which can result in a sore, tender area. Fortunately, there’s an easy solution.
Simply fill the unsupported gap with additional padding. You can use various foams, a folded hand towel or other means to build up this area.
Build it up a bit higher than you think you’ll need – the foam will compress to the correct height. Experiment with what works best for your particular boot or cast. A quick fix is to purchase a replacement Knee Platform Pad and cut it to the correct length. The peel and stick backing makes installation very quick and easy.
Although uncommon, sometimes it helps to add some extra padding at the back of the Knee Platform also. Try different combinations until you find the one that you like best.
Some boots have adjustable air bladders or other hardware mounted on the front of the boot. This hardware can sometimes interfere with proper interaction between the Knee Platform and the boot.
The solution is to disable the air bladder or obtain a boot that has the hardware mounted on the side. Ideally you have a semi-smooth surface on the front of the boot.
