Since the compression is a key part of the Apolla Shocks effectiveness, you may consider selecting one size smaller if you:

• are younger than 11 years of age
• are very petite
• have a very long/narrow foot but have a larger size of foot.

For example:

• an 11 year old who wears a size 6 shoe would choose a size Small Infinite instead of a Medium (based on the size chart);
• A 16 year old who wears a size 6 shoe and has average leg and foot size would choose the recommended size Medium.
