M77 or 511?
Choose the M77 when you specifically want its thicker leather, direct-injected PU outsole and traditional Norwegian military-boot structure. Choose the 511 when everyday versatility, textile lining and a choice of zipper, winter or upgraded 2.0 versions matter more.
511 or Aviator?
The 511 has a more rugged, punk-inspired presence. The Aviator has a cleaner profile and is usually the easier option for customers who want a practical leather boot for regular city movement and travel.
M77 or Aviator?
Choose the M77 for a firmer and more substantial military-boot experience. Choose the Aviator when you want water-repellent leather and Samelin manufacturing quality in a less demanding everyday format.
AIPI or M77?
The M77 is a standardized military design. AIPI boots are made to order in Estonia and emphasize traditional small-workshop production. All AIPI boots use 2 mm natural leather and an EVA insole.
Fit and ordering
Samelin and AIPI boots both tend to fit slightly large. If you are between two sizes, choose the smaller size. Otherwise, compare your foot measurement with the inside-length chart in the Samelin & AIPI Boots Size Guide.
AIPI boots are made to order and are shipped 7–14 working days after the order is placed.
Final recommendation
- Choose M77 for traditional military structure.
- Choose 511 for the broadest everyday range.
- Choose Aviator for a cleaner, lighter everyday profile.
- Choose AIPI for made-to-order workshop craftsmanship.
