Take into account the intensity of your problem. In some cases putting foam in your shoe is enough to get over with the problem. You can find these foams from different shoe stores or get them custom made by ordering them from a sports goods store. If you think that your problem cannot be solved by tweaking of shoes, seek alternatives. Only a person with flat fee would know how much pain it causes. If everything fails, find a shoe that is specifically meant for people with flat feet. Previously, the designs that came for shoes meant for flat people were very dry and looked utterly unattractive. With the advancement in technology, different companies are making highly appealing shoes for flat footed people.
Make sure, you try the shoe that you are comfortable with, before buying it, but you should keep many aspects in mind before buying. Ventilation and lacing being two prominent features of shoes should be catered for. Wear the shoe, and check whether your foot has any breathing space. Wrong type of laces can put a lot of pressure on the top of your feet, and consequently press your foot down on the shoe. Do not get carried away by the looks and design of the shoe, see if it is comfortable, and the laces are not putting any pressure on the bottom of your feet.
Your heel should be well supported by the shoe. Those of you who play sports should see that the shoes have a proper ankle support. The ankle support should not be rigid, that it restricts your movement while playing your respective sport. Numerous companies all over the world are producing shoes at a tremendous rate, so make sure you do not rush into buying your shoes. Do your research, and invest your money when you have found the perfect pair of shoes for yourself.
