How smart insoles helps you find your shoe ?

Many injuries are exacerbated by, or are a result of,abnormal gait or improper support in athletic shoe. No matter what caused injury, improving your gait and chose the right shoe is the best choise. This can so often lead to resolution of pain in the lower limbs or improve your sports performance. There are lots of gait analysis system you can find, but which is the most effect. In this article, we’ll look at some reasons why different gait analysis to choose your running shoe should be reconsider and help you understand how smart insoles helps you find your shoe.

Full-body video gait analysis

Shoe selection. Full-body video gait analysis

A common seen thing is that a store use Full-body video to see if customers have foot inversion or eversion,but this can not be a only one factor to make trainer prescription. Some running stores who have some excellent staff with the knowledge, but this knowledge can not be easily spread. So we hope to find a automatic analysis system to find out the solution.

Ask a group of runners what the reason for video gait analysis is and one of the most common answers will be “to help you choose the right running shoe.” Then they will say ‘to make technique analyse your running ’ but in the end, the most important questions is typically ‘so are these the right type of trainers for me?’ Earlier this year, a study by Saragiotto,BT et al., said: “what do leisure runners think of the risk factors for running injuries?”(2014) highlighted the popular belief among recreational runners that wearing ‘incorrect trainers’ is one of the highest risk factors for injury.

To meet this demand, the last few years has seen an increase in running stores making use of in house ‘video gait analysis’ to help provide customers with the ‘correct type’ of trainer. A quick web search for gait analysis shows most results linking it with some form of shoe fitting service.

Unfortunately, despite the genuine good intention from most running stores, the ‘science’ typically used to translate results from their gait analysis into suitable trainer selection is not science.


Wet foot test and Static pressure analysis

The lack of evidence for the arch-type model has seen many websites a popular ‘Wet Foot Test’ in which runners are asked to stand on a heat sensitive foot pad in order to evaluate their arch type.wet foot test

Static Arch type

Many running stores and websites still promote and use outdated, non-scientific “archtype” models to recommend running shoes.The runners were eventually divided into three groups, each with a pair of suitable shoes:

“High arch” runners are labeled “over supinators” and get more cushioned shoes

The “normal arch” runners are labeled “neutral” and give them a stable pair of shoes

The “low-arch” runners were labeled “overpronators” and recommended a sport control shoe.

As we discussed here, research has conclusively shown that this practice of categorizing runners into three groups based on arch height is way too simplistic. The idea that what your arches do when you are standing on a pad will be replicated once you start running has been disproved.

The arch dynamic condition in  movement

As we observed the user’s condition and our gait analysis report, we found the condition of the arch plays a very important role to help find your shoe. And the arch condition is not the only one evidence to support shoe recommendation, the sensor-embedded insole can get more information like internal impact in shoes,  combine with the intelligent  pain risk area analysis, it will be more supportive to make trainer prescription.

Injury Profiler

Eg.Plantar Fascitis

  • Heel pain with weight bearing
  • Tender medial aspect of plantar (bottom) surface of heel
  • Increased pain with running and walking activities

     Possible Causes

  • Tight calf muscles
  • Excessive pronation
  • Weak intrinsic foot muscles
  • Soft, unstable shoes

Shoe Profile

The shoe midsole should provide maximum torsional stability to reduce medial foot rotation (pronation). Pronation stretches the plantar fascia, resulting in soreness and tenderness on the medial plantar (bottom) of the heel. A midsole with a high to medium heel-to-toe ratio may add further benefits by reducing tension on the calf and plantar fascia.


Neutral (mild pronators) – 3 mm heel lift with or without over the counter arch supports
Moderate to excessive pronators – Custom orthotics with 3 mm heel lift

Many injuries are exacerbated by, or are a result of,abnormal gait improper support in athletic footwear.

Choose what makes you feel comfortable 

The important thing is to find shoes that will reduce risk of injury.  The key is making sure the shoes are comfortable, (see studies by Benno Nigg). The part of work the smart insole do for you is to find out alternative shoes for you in advance. The next is trying on what you chose, going for a run and seeing what ‘feels’ most comfortable.  This may sounds very un-scientific, but the more you try, the better you know your feet.

Ofcourse, make some test and have some options could be a good choice!
