It has been a long time since I did a run in Adidas shoes. When I did a great deal of road running, Adidas was one of my go-to brands but when I headed to the trails and mountains, I defected to other brands such inov-8, Salomon, TNF and so on.
I’d heard lots about the ‘Boost’ technology and was keen to try it. I was a little sceptical about this (what looks like polystyrene balls) Boost technology would withstand the battering that trail brings, but hey, Luis Alberto Hernando has done well with them huh?
The TERREX SKYCHASER is not the lightest shoe on the market, not by a long way at well over 300g for my UK9.5. However, I was pleased that the shoes were ‘true-to-size,’ I the past I had always found Adidas sized small.
The fit is definitely narrow, but not very narrow, in the toe box area and there is plenty of protection with a really great toe bumper for protection – invaluable on rocky terrain. The lacing is via a narrow cord that is pulled tight from the top and then an adjustable stopper retains the tension – it’s very similar to what one sees on Salomon shoes. The excess cord can be stored under a small elastic loop towards the bottom of the lacing section.
The upper has the classic Adidas ‘three-stripes’ on the sides and these also act as the lace-loops from which one pulls the lacing tight. This holds the foot in place and keeps it secure.
The tongue is attached to the upper (my preferred method) as this not only reduces what debris can enter the shoe but also it allows the foot to be held more secure and it also increases comfort. Iv’e said it before and I will say it again, this is the way it should be for all run shoes in my opinion.
The shoes cushioning comes from ‘Boost’ technology and it’s reassuringly cushioned without being spongy. You can see that the insole has a chunk of orange and blue added, this is Adidas’s ‘Pro Moderator’ technology that adds medial and lateral support with additional stability in the midsole. I run in ‘neutral’ shoes and I was worried that these additions would spoil my experience of the shoes – it didn’t! For sure, it provided me with a different feel on the trail and mountains but what I did like was the reassurance it provided when the going got tough – the shoes felt rock solid.
The upper is breathable but most definitely resilient. The Terrex Skyxchaser could definitely be a lighter shoe with a different upper, however, Adidas have obviously decided that this shoe is for tough outings – they don’t want the upper falling apart and in testing, I have to say it’s extremely durable and resistant to abrasion. You’ll also notice the upper has a darker orange colour, this is welding which also adds the increased support of the shoe.
As a cyclist and triathlete, I always chose Continental tyres but this is the first shoe I have used with the legendary German rubber as an outsole – I was impressed! Yes, the outsole didn’t disappoint and the compound provided great grip on dry and wet trail and rocks, it was excellent. The grip profile would make the Terrex Skychaser a great ‘all-rounder’ allowing cushioning and comfort on some road, hard-packed trails and should conditions become wet, the Continual runner really does its job. The profile can handle mud but should conditions become very sloppy, the outsole profile and lug depth is not aggressive enough to provide the grip that say an inov-8 Mudclaw would provide – that comes as no surprise and is not a criticism.
Heading out on the road for my first run, I was struck by how the shoe felt on unforgiving tarmac. The Terrex Skychaser gave me a plush ride with the Continental outsole doing a great job on the hard stuff.
I had purposely chosen routes that involved a multitude of terrain to test the Terrex Skychaser and with Skyrunning courses to hand, this is where I have used these shoes for the last few months – from steep grass banks, hard and dry single-track, scree slopes, boulders, fire-trail, some snow and ice and river sections with slick rock.
In a nutshell the Terrex Skychaser handled all this extremely well with the highlights of the shoe coming with excellent cushioning without a loss of feel from the ground beneath my feet, excellent and reassured grip from the Continental outsole and a snug plush feel from the sock-like fit.
A 6mm drop worked well, for me, my sweet spot is 8mm as I find this to be preferable when I am on my feet for longer. With 4mm and 8mm now being many peoples choices, 6mm sits well as a compromise.
Like I said, I prefer neutral shoes and although this shoe has plenty of ‘extras’ to control my foot, I never found that I was being over controlled, something that I could in a La Sportiva shoe – read HERE.
Cushioning is good without losing feel, 23.5 at the rear and 17.5 at the front makes them ideally suited for a runner who needs some additional protection or who prefers a plush ride.
The overall fit of the shoe is narrow and when the trails are technical and you need reassurance that is a positive. However, if you need a wider toe-box, this is probably not the shoe for you.
It wasn’t an all-singing and all-dancing story. I found the heel box just wouldn’t hold my heel in. When climbing, my heel constantly was coming out of the shoe – a real irritant and a recipe for disaster in regard to performance and the increased risk of blisters. In a conventionally laced shoe, I would have re-laced my shoes and I would have almost certainly used a ‘lace-lock’ method (here) at the top of the lacing to secure my foot. You can’t do this with the Adidas as it does not have two eye-holes at the top and… This brings me to my second issue – the ‘speed-lacing!’ I know many love it and when it works it works, however, with the Terrex Skychaser I just couldn’t adjust the lacing so my foot felt comfortable with the correct tension and adjustment in the places that I needed it. I would that I had to tighten the lacing so much to retain my heel in the shoe that after 15-20 minutes my foot was aching on the in-step due the tension and pressure on the foot. I also found that lower down where my foot bends, I had effectively reduced the width of the shoe and therefore I was getting some pain and discomfort around my toes and metatarsals. I took the shoes off, loosened the laces and then put he shoes back on trying to leave the lower loop lose and wide, the middle lace-loops tight but not too tight and then the top two loops tight and secure – I sort of got to to work but it all felt compromised.
Loads of positives on this shoe but ultimately for me, it’s not a shoe I would use. I say this with regret as I loved the grip, the durability, the overall comfort but the heel box and the lacing made using the shoe a compromise. Because of the heel box, consider trying a half size smaller – it may do the trick? However, you may well find the shoe is then too narrow in the toe box.
