XTRM

Size Guide

The XTRM is limited to the sizes we have on hand.  We are not expecting another shipment.  

Free ground shipping, exchanges and returns in the US.

 



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.

NOTE: 

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.

Great shoes - Impressed!

When I first tried these on, I was a little concerned because my feet didn't feel very supported compared to my other brand of OCR shoes. However, after trying them in 2 races, I love how they feel and the grip they provide on wet surfaces is incredible!

The best OCR shoe

These shoes are great for trails, wet wading along rocky riverbeds, and OCRs. The grip and toe protection are excellent. My only complaint is the tongue is degrading rather quickly so i need to buy new shoes within a year of purchase - still kinda worth it!

Amazing grip

Completed Spartan’s Big Bear Beast in these, I loved them, the grip was insane and a very stable shoe. I ordered a half size up, could probably even go up one more half size, very snug fit. A tad narrow but still ok. Toe box is snug but also ok. First time in 4 Big Bear races that I’ve kept all my toenails. I love this shoe, looking forward to future races.

New Shoes

It took me a while to get VJ XTRMs out on the trails, but now I have. Right out of the box I wore them for the Killington Spartan Sprint. Next up, I wore them for the Spartan Beast in New Jersey. In both cases the shoes performed great. They fit me true to size, did not require a break in period, and as advertised, the grip was outstanding. I look forward to a lot more racing with them.
