In order to get the best out of your running insoles, you must first correctly determine the foot profile you have. This may involve a few simple and easy inspecting techniques which could be carried out by yourself. Many manufacturers of the best arch support insoles too define their products according to the level of support they offer to consumers who have different foot profiles. The simple test involves walking over a sheet of brown or colored paper with wet feet.
High profile
A high profile is seen with those with high arched feet. The impression of your foot print would show a rather complete or obvious separation of the heel area and fore part of the foot. You could also test this by placing your index finger under your foot arch. If there is enough space to spare, it is an indication of a high foot arch. Under such conditions, you would need to find one of the best arch support insoles.
Medium profile
When analyzed in a similar way as above, the impression your foot would have created would have a high definition of the mid-foot region. This means you have a moderately high foot arch. When exposed to excessive or intense levels of physical activity this could lead to overuse of the foot arch and gradually contribute to the occurrence of injuries in the foot region, therefore would require running insoles for added support.
Low profile
Low foot profiles require running insoles as they show a rather full shape of foot when examining the impression created. There is also very little narrowing of the foot shape especially in the foot outline in the mid region. In this instance when one performs the finger test while standing upright you will not be able to pass your finger under the arch of your foot. Such foot profiles make very ineffective shock absorbers and increase tendency of injury.
Requirement Of Custom Orthotic Running Insoles
Some of the best arch support insoles come in custom designs. They are also recommended to be used in the instance you suffer from severe foot problems. Such serious conditions include supination, fallen arches, foot ulcers, and large bunions in foot area. These conditions also require the examination by a licensed podiatrist to find the best possible solution for the condition experienced. Most of the time, these orthotic insoles are made to be rigid to keep the feet in the correct position.
