WYDR STUDIOS SIZE GUIDE
The Perfect Fit
We use the 2E standard, which is the same as WW (wide width). If you wear wide-width brands, stick to the same size. Otherwise, size down from your normal-width size. We also offer complimentary insoles or paddings for personalized fit adjustments to ensure the best fit.
