Footbeds and insoles specially formed for you support your feet in the proper, neutral position. This is crucial for people who over- or under- pronate, and can help those with re-curing foot, ankle or knee pain related to conditions such as plantar fasciitis, Morton's neuroma or runner's knee, among others. Studies have shown that proper support underfoot can help prevent the progression of over- and under- pronation while offering relief from pain associated with foot, ankle and knee strains and injuries.
But you can still benefit from custom footbeds even without acute foot problems or if you have a neutral foot type! Custom insoles add a perfect, custom fit and all-day comfort to all types of footwear. If you spend many hours of your day on your feet, custom support underfoot can help keep your feet and lower back from tiring as easily. Good support for the feet has benefits across your body's entire kinetic chain, encouraging good alignment from your feet and legs up through your whole spine.
If you're still unsure, or want to know more about your foot type, it's an excellent idea to get a foot or gait analysis. These are offered at a variety of sport shops, as well as by many physical therapists, athletic trainers, coaches and doctors.
