VJ IRock+ Trail Running Shoes
For the IRock+ designed a new noticeably wider last, making the shoe a lot more spacious than the original versions. There is a lot more room in the toebox and forefoot area, but you’ll find the same precise fit in the heel and midfoot.
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. The IRock+’s lug configuration closely mimics the original IRock lug configuration, but the surface area of the IRock+’s lugs are a bit larger. VJ’s signature Butyl rubber completes the outsole giving the IRock the world-famous grip it is known for.
The shoe’s midsole is made of a material called LightEVA. Lightness and bounciness are features that are combined in this material, making it a clear choice for this shoe.
The mesh upper of the shoe is made of armored nylon which is durable and protects the foot on rough terrains and adventures. The IRock+ has a soft heel to add comfort and to combat chafing.

[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.
