For the Endurance, Infinite, AMP, and Performance styles, sizing may vary based on foot size and age. You may consider selecting one size smaller if:
1. You are younger than 11 years of age
2. You are very petite
3. You have a very long/narrow foot but have a larger street shoe size. For example: an 11-year-old who wears a size 6 shoe but as narrow feet 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.
However, if you are below our XS size range (below a 12.5) and/or petite for your age. We recommend you wait until you can fit in our Apolla socks. We want them to fit snug so they are effective support.
