SUBU Fit Guide by Style

Packable
This model has a slightly looser fit.

• If you’re at the lower end of a size range, you can size down for a more secure feel.
• If you’re at the upper end, consider sizing up for extra comfort.
• Otherwise, stay true to size.

Nannen & Fline
These styles will soften and mold to your feet with time.

• If you’re at the lower end and prefer a snug fit, size down.
• If you prefer a more relaxed feel, stay true to size.
• If you’re at the upper end, keep your regular size — they’ll naturally adjust as you wear them.

Belt & AMP
These models have a roomier fit similar to the Packable style.

• If you’re between sizes:
  • For a more secure feel → stay true to size or size down.
  • For extra room or to wear with thick socks → size up.
