Find Your Perfect Fit (It’s Not Just Size)

Most people think they need a bigger size…
but in reality, they need a wider fit.

Understanding Shoe Widths

Width	What It Means	How It Feels
F	Narrow	Snug, slim fit
G	Standard	Comfortable for most
H	Wide	More room across the foot
K	Extra Wide	Maximum space & comfort

👉 Quick tip:
If your shoes feel tight at the sides—but long enough—you likely need a wider fit.
