Strengths: I've been using these 4 days a week running to and from work (4 miles each way). Daily temp has been -7 and they are plenty warm enough with winter socks. Running on compacted snow and ice grip is superb. I use a full foot plant to increase contact. Lacing system is very efficient and I've used the same system on my cross country ski boots for 3 years without any problems. I wear 43 in Asics and these are a tad tighter but similar fit. I haven't run for more than 1 hour but I'm confident they would be comfortable for longer runs if you avoid tarmac.
Weaknesses: They are expensive but as I only wear them on snow/ice for shortish runs I hope to get at least a couple of seasons out of them. The studs are deadly on tiled or parket flooring so you have to make the indoor part of your journey on socks - which might be a consideration if you have far to go.
Overall: They were sized at 43 1/3 which gives allowance for thicker winter socks. Lacing system is great -especially handy when your hands are cold.
'Good weight/cushioning compromise. Quite expensive but well made and durable'
Strengths: This is my second pair of Triumphs - previously had the 6 which are still in tip top condition despite the hundreds of miles under them. These fit like a glove and the tongue stays put (my only gripe with the 6). The laces are much improved too and the breathability is better too. If you have Asic shaped feet try these as an alternative. If you're a Mizuno or Adidas shaped foot then these are probably a little too wide to feel secure.
Weaknesses: Maybe a little expensive but I've found them down to £90.
Overall: Top quality training shoe for neutral runners looking for a comfortable and durable product
