Comfortable, durable ankle footwear for the outdoors, for work and for longer hikes – ideal from spring to autumn.

Whether you are heading to work, into the forest or on a mountain trek, CASTOR O2 NM High will not let you down. This higher ankle footwear combines durability, comfort and style in one. The upper of quality Crazy Horse full-grain leather not only looks good but also copes with rougher treatment. The footwear is also breathable, which you will appreciate especially on warmer days – your feet stay fresh and comfortable even during all-day wear.

The higher cut provides the necessary ankle support and reduces the risk of injury on uneven ground. Thanks to the off-road outsole tread with a slip-resistant finish, you can rely on a stable step even on slippery or stony surfaces. The front of the footwear is protected against knocks, which guarantees a longer life even in demanding conditions.

• Durable upper made of Crazy Horse full-grain leather
• Breathable construction for all-day comfort
• Higher cut for better fixation and ankle protection
• Slip-resistant outsole for confidence in demanding terrain
• Toe bumper protection for a longer life

When treating the footwear with an impregnation spray, we recommend covering the plastic eyelets and hooks. The impregnation agent should not get onto plastic parts so that they are not damaged or discoloured.
