New VJ IROCK 4 shoes for orienteering, trail running, OCR

Aggressive grip, now with soft antislip heel

The VJ IRock 4 has been upgraded with a soft antislip heel to make sure that the shoe shapes better to the foot and that the foot stays inside of the shoe even during the toughest of performances. The upper’s design has also seen some small tweaks to enhance the fit of the shoe.

The VJ Irock has long been the most aggressive VJ shoe without metal studs for softer conditions. Its specifically designed lug configuration gives optimal grip when it's slippery but still sheds loose debris that could otherwise become attached. VJ’s signature Butyl rubber completes the outsole giving the IRock the world-famous grip it is known for.

The Schoeller®-Keprotec® upper featuring aramid fibres is incredibly durable and protective with the Fitlock system providing added protection and a personalized fit around the foot arch. With its precision fit and amazing grip, the IRock has long been an orienteers’ favourite but has in recent years shown its class in everything from obstacle course races to the most technical of skyraces.

With performance in mind, this shoe is best suited for shorter to middle distances in softer terrain and is in a class of its own from snowy descents to muddy trails.

Fitlock ensures fit

Innovative system designed to improve the fit of the shoe, making it feel like a part of your body. Integrated with the lacing, the Fitlock system tightens the shoe on the inside and under the arch of your foot.

Schoeller Keprotec® upper

Aramid fibres within the fabric makes the shoe amazingly durable and gives excellent protection.

Aggressive grip

The Superior Contact -outsole is produced from our own special rubber and ensures grip on all surfaces. Aggressive 6mm lugs provide grip in the toughest of conditions but also allows you to enjoy running on flat areas.

  1. Place a sheet of paper on the floor and against a wall.
  2. Make sure that you are wearing the same socks as you would typically wear with these kinds of shoes.
  3. Wearing these socks, stand on the sheet of paper with your foot perpendicular to the wall and your heel against the wall.
  4. Then ask your friend to draw a line just in front of the longest point of your foot. Repeat with both feet and take the longer distance to determine your size.
  5. Use a ruler and measure the distance between the wall and the line that you drew to find your size. If you are between sizes, choose the bigger one.

The sizes on the table are racing fit with just a couple millimeters of free space on the toebox. If you prefer more space, go for the bigger size. If you have questions or need help with sizing please contact, we are happy to help.
