Fit Recommendations
- Between sizes? → Size UP — carbon soles don't stretch; tight shoes cause numbness
- Wider feet / high instep → Always go one full size UP
- Thick winter socks → Add ~½ size (CW1 Winter already has extra lining)
- BOA® closure → Fine-tunes fit; choose correct base size, don't size down expecting to tighten
- Women: subtract ~1.5 from US Men column → e.g. EU 38 ≈ US Women's 7
