Size Guide

    Made for extreme trails...

    The VJ XTRM is made for rocky and technical trails where grip, stability, and durability are mandatory.  

    The aggressive lugs grip dirt, mud, rocks and anything you run on. The super tough upper is a custom kevlar and polyester weave which provides extraordinary protection and durability. The sole has cushioning units in the front and heel for comfort and a full length rock plate to protect you on tough terrain. 

    The XTRM was built for obstacle course racing, trail and sky running and swim run. Use it for tough, demanding terrain in all conditions. This shoe wants to get dirty.



    • Built on a medium last
    • 48% Kevlar and polyester blend upper
    • FitLock for mid sole stability 
    • Cushioning units in front and heel
    • Fiberglass stability control
    • Full length rock plate in midsole
    • Outsole is 100% Butyl-rubber
    • Strengthened rubber toe-cap
    • Aggressive 6 mm lugs in outsole
    • 24mm/20mm stack height - Total with Lugs
    • 4 mm drop
    • Weight (US 8.5): 8.8 oz (250 g)


    The XTRM seems to run true to size for length. Some have felt that the toe area is a little snug. Going up 1/2 size seems to be the perfect fix. If you are between sizes, go with the larger size.

    A little tight

    I would order a half size larger. They are unusually tight for my normal size 12

    Great shoes

    Really love them in the technical terrain. Great grip and comfortable. I actually bought another pair as well as 2 of a different model.
    Really happy with them.

    Love These Shoes!!!!!

    These shoes are AMAZING! I bought them for hiking and absolutely love them. I also have a pair for mud runs (obstacle course racing.) Totally with the buck!

    Perfect Fit

    I wear 10.5 in Nike and Brooks, got these in 10.5 and they fit like a glove. So far I’ve ran two five mile runs and love them! No break in issue right out of the bus they’re great!

    OCR shoes

    Great custumer service.Order came quick.
    I was looking for a good OCR shoe, that's why i ordered all three
    The iROCK3 is very narrow and the XTRM is also too tight even with a half size up.
    The MAXX fits on like a glove,but the lugs are much smaller.
    I wish VJ made a shoe with the MAXX's top part and the XTRM's sole.(hope soon)
