Shoes and orthotics usually go hand in hand but you would be surprised to what patients deem as a sensible shoes for their new shoe device to live in.
An orthotic are designed, whether custom or not, to help keep your foot in a certain position which it should be at, at the most neutral point when you walk. If something interrupts that then your orthotic will not work as well.
So the shoes needed for your orthotics need to have a fastening- lace or Velcro. Slip on shoes or high heels will not work that well because the orthotic is not stable. Also those types of shoes are probably not helping the reasons why you need orthotics in the first place.
2- It depends upon your day to day life. If the shoes you need to house the orthotics in are for sports, then take a sports shoe to where ever you are getting your orthotic from and test to see if it fits. Sports shoes have a natural arch in them (which is uncomfortable for some people) so you might have to take the lining out for your orthotic to fit.
3- Also your shoe and lifestyle dictates what type of orthotic you need. Most people just need a basic one with a bit of cushioning. However if you are a runner then your orthotic would need to be softer and be able to fit perfectly within the shoe.
4- If you wear your orthotic only when you wear a certain type of shoe then you need to consider whether you need and orthotic or not, or whether you need to change your shoewear. This is because the orthotic will not be working as well as it should if it is only in a pair of shoes for 2 hours only.
5- Most shoes can handle a pair of orthotics. But always take the main pair of shoes that you want the orthotic to fit to the person creating the orthotic.
6- Cost of shoes do not represent the "greatness" of a shoe. Some low cost shoes are equally as good as very high priced ones. So breaking the bank to find a shoe that fits your new orthotics is really not needed.
7- When you have an orthotic it reduces the depth of the shoe. So that tight shoe that you want an orthotic in will not fit at all and give you issues with your feet. Also the shoe itself needs to be deep enough. Some patients have hand their foot come out of the shoe when they bought an orthotic.
8- An orthotic will only work if the system works. Your body is a system. If you have tight muscles then this reduces the orthotic effectiveness.
9- A one off issue? If you had an issue, like plantar fasciitis, and you get orthotics, that doesn't mean that you need orthotics for life. Once that simple issue is resolved then you can start to reduce the amount of time with your orthotics. If the pain comes back (noticing that you have got good shoes and havent reverted back to bad shoes) then probably you will need them for life.
Just making sure that the shoe is capable of housing the orthotic is the main point I am trying to get across. That it is sensible and that it is what is classed a "normal shoe". If you can get running shoes then that would be great because they are designed for walking and adding an insole is building upon a good foundation to start with.
