Men's CSA Oshawa II Waterproof Boot (Carbon Fiber Toe)

C$200.00

  • Size Guide
Please choose a size! Please choose an inseam!

Designed for toughness, and now even lighter. The Oshawa II combines outdoor style with advanced features, including a flexible, non-metallic puncture-resistant plate and our new carbon-fiber safety toe that’s 15% lighter than steel.

  • Left and right asymmetrical carbon-fiber toes
  • KEEN.DRY waterproof, beathable membrane
  • KEEN.KEY-TECH FLEX: contoured underfoot support provides structured stability and comfort
  • Non-metallic puncture resistant midsole plate—CSA certified. Meets CSA Z195-09 Grade 1 standards for protection
  • Torsional stability shank (TSS) for midfoot support
  • Contoured heel lock
  • Reflective webbing for additional safety and visibility
  • Meets ASTM F2913 SATRA non-slip testing standards
  • Cleansport NXT™ for natural odor control

We've carefully selected leather uppers designed to last. Then again, if you're wearing your KEENs daily, they won't always be scuff and dirt-free. To treat day to day wear and tear, especially on lighter color leathers, we recommend using a leather cleaner and conditioner, found at most footwear dealers and/or shoe repair shops.

    Comfortable and light enough to wear all day. Roomy around the toe, was able to wear straight out of the box. Keep making this style subtle and looks good.

    Comfortable work and hiking boots.

    Comfortable right out of the box. Looks good, not too flashy, subtle style. Durable enough for work load, lighter than steel, can wear all day. Roomy especially around the toe. Will buy again if on sale. Keen keep making these boots, they are a hit.

    I love these boots BUT not wearable after 5 months

    This is a comfortable and durable work boot, the best that l have had in 6 years of landscaping work outdoors. Unfortunately, the fabric lace loops have worn out in two loops on each shoe, so that effects the ability to tighten up the laces properly. The lace loops started to breakdown after 4 months and then torn through after about 5-6 months. The rest of the boots, including the soles are in great shape. These have the potential to last for two or more of our work seasons if the lace loops were stronger. Keen should consider upgrading the six bottom fabric loops to the same plastic reinforced fabric loops at the top of the boot. Those ones look durable and still in top condition.

    Great Comfortable Work Boot

    The moment I slipped these on they were comfortable, and 14 hours later my feet were still comfortable no aches or pain. Proved dry in the water and wears like a supportive hiking boot. I am very happy with my Oshawa's.

    Great boots

    I purchased these boots a few weeks ago to wear for light commercial and residential plumbing work. I'm very happy with my purchase so far. The tow cap is extremely durable and able to withstand frequent kneeling. The locking lace loops are extremely convenient for service work when you have to be in and out of a customers house frequently. The boots are extremely comfortable and despite other reviews I've found the grip to be adequate on slippery surfaces.
