For the dancer whose foot is between widths, the Suffolk Sock Liner may be the perfect solution.
The liner is a 1-mm thick piece of high quality suede material, shaped to fit over the insole of your pointe shoe. This helps fill in any excess width and/or profile of the shoe, providing for a better fit.
Note - one liner is included per package. If liners for both shoes are needed, order two of this item.
