How do I know which arch height, size or variant to choose?

Arch height can be difficult to determine based off a purely static position of the foot as this fails to take into account the amount your foot may change shape under heavy loads. Our carbon InnerCore is designed to have some flex to accommodate this shape change although there is still the potential for it to feel like too much pressure if too high an arch is used. In the inverse situation an arch shape that is not high enough will not provide the sensation desired.

We provide an arch height guarantee, so that you can rest assured you will end up with the most suitable contour for your feet. See our SemiPro Selection page for assistance.

As far as choosing your width and thickness of device, it is advised to compare to your current insole size and order the closest size to this to achieve a similar fit. You may also choose to select the Thin variant to gain a bit more volume inside the shoe. Generally, if between sizes or widths we recommend choosing the larger of the two and trimming the EVA at the forefoot if required. Some tips for this can also be found on our SemiPro Selection Sizing page.

Find Your Fit

As podiatrists, we are no strangers to the intricacies of foot form and function. That's why we developed a range of unique profiles for our much-loved SemiPros. Rather than arbitrary changes in height across our Low, Medium and High inner soles, each profile has a unique contoured shape to suit key features of the foot type for which they are designed.

This three-step guide is designed to help you select your perfect profile.

Step 1: Arch Profile Observation

Begin by observing the static, non-weight bearing shape of your feet:

Observe the medial aspect of your foot (from your heel to big toe) while seated with your ankle in a neutral position and your feet flat on the floor. Because this is a non-weight bearing observation, this should be carried out with minimal and equal weight distribution.

Step 2: Mobility Evaluation

Second, evaluate the degree of mobility present in your midfoot to determine how your feet change shape when they are loaded.

Perform a series of calf raises, comparing how pronounced your medial arch shape is at the beginning and end of each raise. Typically, a more mobile foot will display a pronounced shape at the end of the calf raise movement. Less mobile feet will see little shape change.

Step 3: Size, Width and Volume Selection

Use our downloadable sizing guide to match your current inner sole with your chosen SemiPro:

Standard

Wide

You can choose a Standard or Thin backing option at checkout to maintain or increase the space in your shoes. Simply measure the thickness of your current inner sole and select accordingly.
