Foot supports are widely used to take care of a range of biomechanical disorders of the foot and leg. These foot orthoses are inserts that are used in the footwear to attempt to change alignment of the feet in such a way that they help conditions in the foot and leg. These problems vary from, for example, plantar fasciitis in the heel to shin splints that can happen in the legs of athletes. All the research evidence shows that the clinical outcomes with foot orthotics are likely to be beneficial and most people that have foot orthotics are happy with them. Nonetheless, foot inserts are only ever do worthwhile if you actually wear them. You do need to have proper shoes to use them in and wear them enough for the disorder they were issued for to get better.
Among the problems with foot inserts is that you need to use them in shoes. This is often a problem if you do not like wearing footwear or live in a warm climate in which the wearing of footwear is problematic. In these climates people like putting on jandals (known as ‘thongs’ in Australia) which you can simply not wear with a foot supports. There are numerous alternatives that you can get. Among those is to restrict the time that you're not wearing the foot orthotics, so that you wear shoes with the foot orthotics enough and don't wear the flip flops too much so that the painful condition does not occur. An alternative is to use such things as the arch support sandals or jandals like the the Archies from Australia. These have some arch support included in them and may typically be used rather than foot supports. Footwear much like Archie Thongs will often not be as effective as a properly made foot supports, but they would be more than adequate to supplement them and use when the proper footwear cannot or will not be used.
