Not optional for winter. Most M77 customers order these at the same time. The M77 Inner Socks are engineered specifically for the M77 last — they fill the wide-cut boot, reduce movement inside the shaft, and add meaningful warmth in cold conditions. Multiple NATO armies issue them alongside M77 boots as standard winter kit. Why these socks Designed for the M77 last — fits the wide cut of M77 boots without bunching or slipping NATO winter issue — used by military personnel across Germany, Norway, Finland, Estonia, and Latvia Sizes 32–52 — matches the full M77 size range Reduces break-in friction — the extra layer cushions the stiff leather during the break-in period Extends insole life — reduces direct contact wear on the M77 anatomical insole 2-year warranty — same Samelin quality standard as the boots Fit and sizing Order the same EU size as your M77 boots. If you are between sizes, go one size down. The sock is designed to be snug inside the boot, not loose. Frequently asked questions Do I need these if I already have thick wool socks? Thick general-purpose socks work, but they are not cut for the M77 last. The Inner Socks are shaped for the specific shaft height and volume of the M77 — they stay in place and do not compress unevenly. Can I use these with other boots? Yes, but they are optimised for the M77. The sizing is based on the M77 last, so fit in other boots will vary. Do these add significant bulk? They add a thin-to-medium layer. The M77 is sized with extra volume — these socks fill that volume correctly rather than creating tightness.
