Is it a sock or a Shock?! Let us clear up any confusion… dancers call them SHOCKS because they are the benefit of a SHoe and the comfort of a sOCK…with the added option of grip, they easily replace their footwear making them so much MORE than a sock. BUT to everyone else they are the best compression sock in the world. So while we started for dancers, you may see Shocks and socks...just know they are the same thing and not a typo. 😉

The feet are fickle (and so are your preferences). Each person will fit their Socks differently…so below the charts are size GUIDES…SEE BELOW FOR SIZING TIPS to help get you in your best fit!

*PLEASE NOTE: Our socks may not be easy to get on if you are not used to compression socks, and may not work for wide feet. If you have extra wide feet, we recommend waiting to purchase until we come out with our WIDE options and also plan to release XXL sizes this year.

Tips for Sizing

  • The Alpha: is a snug toe fit and the Infinite Shock has a freedom fit toe.
    • If you have a very wide foot and is on the top end of the size range listed, you may choose to go up a size in the Alpha.
  • The Performance Shock/AMP Shock fits like the Infinite, but the size chart IS slightly different so please take note! The top of each size range is borderline, here are tips to help you determine your best fit.
    • Foot size, narrowness and age may change the size up or down.
    • You may consider selecting the smaller of your border line size IF:
      • You are at the low end of a size range, and/or have a narrower foot than average or are petite boned if you prefer a snug fit in the toes you may want to go down a size but if you like wiggle room, go with the size that is recommended.
    • You may consider going UP to the next size if you are at the TOP of the size range and have a wider foot or want more wiggle room.
  • For the Infinite Shock sizing, foot size, narrowness and age may change the size.
    • You may consider going down to the smaller size if:
      • You are at the low end of a size range, and/or have a narrower foot than average or are petite boned if you prefer a snug fit in the toes you may want to go down a size but if you like wiggle room, go with the size that is recommended.
    • You may consider going UP to the next size if you are at the TOP of the size range and have a very wide foot or want more wiggle room.
    • The Infinite has the MOST freedom in the toes of all sock styles…so with the above rules also consider if you prefer a snug fit in the toes (go with the smaller size you are borderline for) or want some wiggle room (go to the larger size you are border line for).
    • Also note, the Infinite hits mid-calf and gives your calves a nice snug hug. Many people crave this support and love what it does for calf aches and shin splints…others find it claustrophobic. If you would not like the profile of the mid-calf, consider going down to the Performance or AMP.
  • The Joule Shock:
    • If you are at the bottom of the size range and have a very short arch (the length of your overall shoe size is primarily made up of the ball of your foot and toes) or are very narrow feet/petite boned, go with the smaller of the two sizes.
    • If the Joule loses it shape, wash it with normal care instructions and it should regain its shape nicely.
    • Please watch our quick How To Wear (www.apollaperformance.com/pages/how-to-wear) tutorial videos to see how to put them on, because there is a right-side-up and upside down to wearing them and can effect how they feel.
  • The K-Warmer Shock:
    • Measurements are given as a range that it may fit. Most likely starting about an average 13/14 yr. old female on thru an adult petite/average male dancer. However, it may vary based on personal preference.

Please watch our quick How To Wear tutorial videos to see how to put them on.
