A new VJ Sport shoe is always exciting, this time, the XTRM2, which I guess is not really a new shoe but a re-working of a VJ classic. The XTRM has been a popular shoe in the trail, fell and mountain running world for a very long time, sitting in the middle ground of the aggressive iRock and the MAXx.

The key to any VJ shoe is the outsole and the incredible grip that this outsole provides. The XTRM had 4mm lugs, the same as the MAXx but not as long as the iRock and therefore it was the ideal shoe for say skyrunning.

However, two things were often heard when fellow runners discussed the XTRM:

1. I just wish there was a little more cushioning.
2. I wish they could be just a little wider.

Well, the XTRM2 addresses both these issues and brings a couple of newer developments.

THE SHOE

You should never judge a shoe by how it looks, and yes, some of you may love the look of the new XTRM2, I do not! Red is always great and when combined with black, superb. Look at the VJ Sport iRock HERE – now that is a nice-looking shoe! But this XTRM2 looks like someone had a little too much alcohol and dope in Hawaii and then designed the shoe. It’s a ‘me’ thing. Sorry.

Gladly, I can get past the looks because I know that a VJ Sport shoe will do all that I want and do it well.

As mentioned, the XTRM2 is designed to fit between the iRock, which is a short distance and soft-ground shoe and the MAXx which is a longer distance trail/ mountain shoe. Of course, there is now the ULTRA too. That is for the long stuff.

Quite simply, if you loved the XTRM, the XTRM2 is going to make you smile. I had no issues with the original version, however, straight out of the box I welcomed the extra cushioning and the slightly rounder, more spacious toe box.

Drop is 4mm with 10mm cushioning at the front and 14mm at the rear. For perspective, the iRock has 8/14mm and the MAXx 12/18mm.

With a reshaped last, CMEVA cushioning and a rock plate, the XTRM2 is the perfect mountain/ skyrunning shoe.

Pulling the shoe on there is a notable difference with the tongue, it is fastened on both sides. One of the issues in the previous XTRM and MAXx for that matter, was the tongue would move when running – often moving to the left or the right. This has now been addressed and in all my test runs so far, the tongue has remained in place and secure.

Fitlock is a VJ Sport secret weapon and is one of the USP’s of the VJ brand. Once you have put your foot in the shoe, as you tighten the laces, the Fitlock grabs hold of the instep/ arch and holds it tight and secure – exactly what is required in mountainous and technical terrain when you need the shoe to be precise. With the more spacious XTRM2 toe box, this new Fitlock is even more welcome. I was initially worried if I would lose some of the precise feel at the front end, not so, the Fitlock compensates.

The lacing is classic with 6 eyelets and the addition of a 7^th eyelet on both sides should you require to lock lace or similar. There is reinforcement here ensuring that the laces can be pulled tight without causing any issue to the upper.

The upper is Swiss Schoeller Keprotec® which is more durable than previous incarnations of the XTRM and it is also more pliable, allowing it to fit the foot better. Look at the old XTRM HERE – I reviewed this shoe back in 2018. Notably look how different the upper is… The original XTRM had many reinforced panels on the upper with a solid extension from the toe box and heel area. It’s a major change. I wondered, by contrast, if the new XTRM2 would feel less secure and sloppy – no. Foot hold has been excellent. The upper is excellent and repels moisture, water and mud.

The heel area is slightly padded but not excessively, importantly it holds the foot and there is no slipping when climbing.

Toe protection is adequate but could maybe be a little more? Certainly, in a skyrunning scenario when rocks, boulders and hard mixed terrain will be encountered.

The outsole is a notable difference, the previous XTRM had 4mm lugs, they have now been increased to 6mm and in doing so, they now match the iRock. This is a key and notable change. For me, I would now only need an XTRM2 and MAXx (which has 4mm lugs). I do appreciate though, that the narrower and more precision fit of the iRock would be preferable for some.

The outsole pattern is newly designed to optimize grip on all terrains and with the 6mm lugs, you now have an outsole that can handle softer ground. There is little to say about the grip of the outsole, VJ have the tagline ‘bestgripontheplanet’ and it is. No outsole from any other brand matches the grip, wet or dry, of a VJ outsole. However, be warned, that grip comes from a wonderful soft and grippy superior contact – it will not last and last and if you run too much road, that longevity will be reduced greatly. You cannot have amazing outsole grip and long life.

There is a torsional rigidity in the shoe that is very noticeable when running on uneven and rocky terrain. If you have the Fitlock laced up and tight, the XTRM2 gives superb precision.

Flex and life are superb, and the propulsive phase is superb. There is a real ping behind the metatarsals when pushing off.

Weight is incredible, VJ list 250g for a UK8. My UK10 is 289g.

I am always a UK9.5 in test shoes, however, I have noticed with extended use in VJ that I have often wished I had gone a half-size larger, so, with the XTRM2 and SPARK (review to follow) I decided to go to UK10. It was a good choice; I have found that extra space welcome. So, you may want to check this when purchasing.

CONCLUSION

Fitlock and a VJ outsole and you have a perfect shoe when precision and grip are required. The XTRM2 with a new upper, a new last, more cushioning and lugs increased to 6mm, and you now have the perfect trail/mountain and skyrunning shoe for short to middle distance. There are few shoes out there that can compete with VJ when this combination of elements is required. It is highly recommended.

Are there any negatives? I found prolonged running on hard surfaces (gravel road a good example) eventually tiring, but that is no real surprise. The outsole is soft and sticky and if you use on the wrong terrain, it will not last. I really dislike the look of the shoe, which is a petty thing to say, but the ‘look’ could put some people off before ever having the chance to run in the shoe and then find out how good it is. However, I may be alone in finding the look displeasing?

Ultimately, the XTRM2 is a superb shoe with incredible fit and grip.
