The imbalance in the muscles causes the plantar fascia to tighten and spasm to help support the foot. The calf muscles are also commonly involved as often are other leg muscles in the thigh and hip. If you have plantar fasciitis you are under more stress than you can handle – whether that be from overtraining (too much anaerobic activity, or lack of an aerobic base), working too hard, dietary stress (too much sugar, not enough protein or nutrient-dense foods), emotional stress, or other physical trauma/stress – which can be anywhere in the body, not just in the foot.Įven a pair of poor-fitting pair of shoes can cause plantar fasciitis. There are much better ways to correct plantar fasciitis than investing in a pair of oversupported shoes that won’t do justice to your feet anyway. Roger Sheffield on the Kuru site, “I’ve developed plantar fasciitis and my Kuru’s are by far the most comfortable shoe as I deal with this condition.” Deal with this condition, but don’t address the problem? Hey, just listen to an exact quote from Dr. But wearing improper foot wear will create and/or support plantar fasciitis. Orthotics, braces, and Kuru, will not cure your plantar fasciitis because they don’t do anything to fix the problem. Often muscle trigger points (sore spots) can be found in the calf muscles, especially just behind the tibia – that’s your main shin bone as people know it. As with most pain, anti-inflammatories are prescribed-and they only further mask the symptoms. It is not a very comfortable way to sleep and the therapy is about as beneficial and primitive as a caveman making a square wheel. Today this is treated conventionally with “night splints” to help stretch the fascia, and reduce muscle contracture. The pain can be sharp over one specific point, or more diffuse throughout the fascia (sheath of muscle) of the foot. Plantar fasciitis symptoms are usually worse in the morning, and tend to ease off or go away as you walk throughout the day. So when the tibialis posterior muscle doesn’t function well, the arch fatigues to some degree, and plantar fasciitis results. This muscle starts just below the knee and extends all the way down to support the main arch of the foot. Plantar fasciitis is due to a weakening of the tibialis posterior muscle, which sits behind your shin bone.
Yes, when someone does develop heel pain or pain near the arch and it’s diagnosed as plantar fasciitis, support typically does help. Kuru’s primary marketing pitch is the plantar fasciitis angle. Plus, the arch is designed to bend, not be supported. Balance, stability, and fine motor skills all rely on this proprioception from the arch – not from your orthotic Kuru shoes. Clearly nobody at Kuru bothered to look at the actual biomechanics of the foot and realize at least one simple fact – the arch is a major source of proprioception – which ultimately means that it tells your body where you are in relation to the ground. This is interesting because in a way, it also wrongly assumes that everybody has a similar arch depth in their foot, and, despite any evidence, wants the arch of the foot to be supported when walking, running, or even standing.
Its motto is “if your foot isn’t flat, then your shoe shouldn’t be flat”. Kuru shoes are based on the idea that a person’s foot should be supported completely and entirely throughout the shoe. Yet ironically, the Kuru says right there on its website that its design philosophy is “less is more.” It also says it’s “the world’s most anatomical footwear.” I don’t believe either claim. Its complete product line of walking and running shoes feature a reinforced arch, energy-return foam piece, a whopping big insert called a HeelKradl, a molding sockliner, EVA midsole, and the dual density outsole. If you’ve had plantar fasciitis, you know what an icepick-jabbing-in the-bottom-of-the-foot nightmarish pain it can be. Kuru’s “remedy” is more shoe and lots of it. In this case, Kuru has planted its feet-first flag on plantar fasciitis, the scourge of runners. Kuru Footwear is the latest example of superficially treating the symptoms of a foot injury without addressing the underlying cause.
