There is no one-size-fits-all answer to this question since running shoes fit orthotics differently for each individual. However, generally, running shoes with a wider toe box fit orthotics better than running shoes with a narrower toe box. Additionally, running shoes that are made with a stiffer construction tend to fit orthotics better than running shoes that are made with a softer construction.
There are three factors to consider when trying to fit running shoes with orthotics.
Type of Orthotic
First, the type of orthotic you use will affect how much room you have for your feet. Some orthotics are designed to sit in the arch of your foot, while others don’t have much arch support.
The shape of your foot
Second, the shape of your foot changes over time. If you have flat feet or high arches, you might need a higher heel-to-toe drop in a running shoe than if you have low arches or flat feet.
Size and style of shoes
Third, different brands and styles of shoes come in different sizes. Find the right fit by trying on several pairs and allowing plenty of time for them to break in.
When fitting running shoes with orthotics, look for a couple of key features: A heel cup that fits around your heel and supports the arch. This is especially important if you have flat feet or high arches. A midsole made from a material that molds to the shape of your foot. This is especially important if your feet change shape over time. Orthotics should be fitted snugly but not tight enough to cause discomfort or pinch nerves around the Achilles tendon.
