Foot orthotics are generally traditionally used to treat a range of biomechanical conditions of the foot and lower leg. These foot supports are inserts that are used in the shoe to attempt to improve alignment of the feet in a way that they help ailments in the feet and leg. These problems range from, for example, plantar fasciitis in the heel to shin splints that may occur in the legs of athletes. All the scientific evidence shows that the clinical results with foot orthotics are likely to be beneficial and most people that have foot orthotics are happy with them. Nevertheless, foot inserts are only ever do any good if you actually wear them. You do need to have proper footwear to wear them in and wear them for long enough for the condition they were issued for to get better.
One of the difficulties with foot inserts is that you simply need to use them in shoes. This may be a problem if you don't like using footwear or reside in a warm environment in which the wearing of footwear is difficult. In these climates people like using jandals (known as ‘thongs’ in Australia) which you can simply not wear with a foot supports. There are several options that are available. Among those is to restrict the time that you are not using the foot orthoses, so that you wear shoes with the orthoses enough and don't wear the sandals too much so that the painful condition does not occur. An alternative is by using things like the arch support sandals or jandals like the Archie Thongs from Australia. These have some arch support constructed into them and can typically be used instead of foot supports. Footwear much like the Archies will usually not be as effective as an adequately made foot orthotic, however they could be more than sufficient to supplement them and use when the proper shoes can't or will not be used.
