The bottom of my Shocks are pilling, is this normal?Updated a year ago

Apolla Shocks are made with high quality performance yarns to create long lasting, durable, and effective supportive socks. However, when worn in shoes or carpet pilling may occur. This does not lessen the effectiveness of the support for the recommended 6-9 months of life of the Shocks. Washing your Shocks in the recommended mesh bags will help prevent/reduce pilling as well. Just as any dance shoe or footwear, the bottom of the Shocks may get worn down or dirty, it is recommended to have a pair of rehearsal Shocks and a pair of “stage ready” Shocks if there is concern for the appearance.
