With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Karhu Fusion 2.0 Shoes Gunmetal Jet Black




Karhu's story began just over a century ago when a small workshop was set up in downtown Helsinki by Ab Sportartiklar Oy. This workshop's first product was sports equipment such as javelins and skis made from locally sourced birch. This Finnish birch had a big advantage in that it was lightweight and flexible, and 4 years later they would change their name to Karhu - Finnish for "Bear". It didn't take long to realise that all every piece of athletic gear they made was top class, so by the 50s they were making their own trainers.

The uppers of these sneaks are made from a versatile blend of durable suede, tough leather and a lightweight and breathable mesh. The lining is heavily cushioned and made from a soft textured textile fabric. This padding is also present in the tongue, and the moulded sockliner is lightweight yet shock-absorbant.The midsole is made from an expanded polyurethane which is extremely comfortable and provides a smooth ride, and sits on a tread made from a tough rubber which is highly grippy.

Other details include metallic eyelets with round laces and breathable perforations down the sides. The heel has a pull tab and branding is included on a woven tag to the tongue and an embossed name to the back of the sole. Finishing the look are reflective details to the toe and heel. In recent years Karhu's athletic heritage has been elevated to new heights of fashion, so get on the trend, it's here to last.

  • Synthetic mesh paneling

First, don't measure your feet in the morning; feet often swell during the day due to heat and activity. For the best fit, measure your feet at the end of the day.

To measure your shoe size follow these instructions:

1Heel - Toe Length

Place a piece of paper on the floor with one end against a wall. Stand on the piece of paper with your heel against the wall. Mark the piece of paper where your toes end with a pencil. Measure from the end of the piece of paper to the mark you created with your pencil and compare the measurement to our sizing chart.
