Fit & Sizing Notes
Sidi boots use European sizing and are designed to offer a secure, supportive fit for riding.
The Adventure 2 has a structured feel through the ankle and shin for protection, with adjustable buckles and calf fit to fine-tune comfort.
If you are between sizes or prefer extra room for thicker socks, consider sizing up.

Still not sure on sizing?
If you’re unsure on sizing or between sizes, we’re always happy to help — especially with boots where fit really matters.
The Sidi Adventure 2 Gore-Tex CE Motorcycle Boots are built for riders who spend serious time on the bike — whether that’s long-distance touring, road riding or heading off the tarmac into proper adventure use.
They’re designed to deliver consistent support, protection and weatherproofing when conditions change and the miles start adding up.
A Gore-Tex® waterproof and breathable membrane keeps water out while allowing airflow on longer rides. The Technomicro and suede upper balances durability with flexibility, while the flex system and adjustable buckle closures allow controlled movement on and off the bike.
Protection runs throughout, with a reinforced shin plate, structured ankle support and a rigid heel cup for stability. That matters when you’re standing on the pegs, riding uneven ground or covering distance fully loaded.
A full-length inner gaiter helps keep water and debris out, and the non-slip sole provides grip when you’re off the bike on mixed terrain.
