Will they fit into my shoes?

Cobra9 SemiPros will be compatible with just about every shoe on the market straight out of the packaging.

The low profile nature of the underside and dual density EVA should keep the volume of the shoe similar to the standard innersole and the carbon InnerCore shape has been designed to ensure they're working with the shoe not fighting against the carbon sole and heel cup or rocking inside the shoe.

If required, the front, soft edge can be trimmed to be the perfect fit for your shoe.

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.
