Your orthotic insoles will take up space in your shoe, but it is generally not necessary to go a size bigger, but please do not buy a shoe that is already tight on your foot. If you already have orthotics, we advise that you take your orthotic insoles with you when trying on new shoes. Generally, shoes used for wearing orthotic insoles should be flat on the inside so that the angle and the position of the orthotic insoles are not compromised.
When buying a sandal, it is advisable to select one with a closed back or one that has an adjustable ankle strap which should help to comfortably accommodate your orthotic insole. We can provide you with Velcro to fix the orthotic insoles to the base of the sandal. Other factors to consider when buying a closed shoe for orthotics is that the heel cup depth of the shoe is deep enough to prevent heel slippage and that the toe box of the shoe is deep enough so that excessive pressure is not applied to the top of the foot.
The orthotic insoles must fit properly in the shoe for both comfort and function. Please bring the shoe and the orthotic insoles in for us to adjust if necessary.
