VJ IROCK 3 – THE GRIPPY ONE – 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.
Now in its third generation, updates include improved toe protection, lighter Fitlock system, and improved laces.
With its precision fit and amazing grip, the Irock has long been an Orienteers favourite. In recent years shown its class in everything from obstacle course races to the most technical of skyraces.
VJ Irock 3 designed 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.

[accordion-item title=”▸ How to measure your foot”]
For the best fit, measure your foot at home before ordering. It takes 2 minutes.
Place a sheet of paper on the floor against a wall.
Put on the same socks you would wear with these shoes.
Stand on the paper with your heel touching the wall, foot straight.
Ask someone to mark the tip of your longest toe. Repeat both feet — use the longer measurement.
Measure heel to mark in cm. Use the size chart below to find your size. If between sizes, always go larger.

[accordion-item title=”▸ Shoe fit scale”]
VJ have graded the fit on all shoes from 1 to 5 to help you find the perfect fitting shoe.
Wide
Grade 1 represents the most precise and narrow fit. Grade 5 has the widest fit.
The lower the number, the narrower the fit — essential for fast technical running where minimal foot movement matters. Higher numbers suit wider feet or those wanting extra comfort, and are often preferred on longer distances as feet tend to swell.
