Mike P (9.5): I have V4. The Superiors in 9.5 feel a bit short to me, I’d likely go with a 10.0 for sizing comparable to my Timp 4’s in 10. Superiors are more stable due to being much lower to the ground. That said, they are much less cushioned and you will have much more ground feel, whether you like that or not. The Superiors version of MAXTRAC outsole and lug pattern offers much better traction. Fit 10: Fit is true to size, doesn’t feel sloppy, and hugs the midfoot while still allowing ample room in the toebox. Works well even with a medium-volume insole or orthotic if you need it. Mike P (10.0): The T9 has a wide enough toebox to rival the Timp 4. I find it well suited to longer distances in terrain more technical than the Timp 4 can handle. Clear win for the T9 in the traction department - Asics Grip is great. The Timp 4 feels much more cushioned underfoot, and also feels like a more fun ride in moderate terrain. The laces are reflective, which makes them light up in low light conditions to give a little bit more visibility on the winter commute when it comes round again. I find the overall fit of the upper to be really great, almost slipper-like in comfort and feel. This may be a bit of a detriment on more technically oriented trails, but it’s great for most anything else. The sides of the upper wrap further over the top of the foot, so the gap the laces span is shorter.

The previous Timp was just kind of there, somewhat technically oriented, but not quite comfortable or cushioned enough to appeal to most. Altra seems to have focused on the technical mountain side of the equation with the new Mont Blanc, and moved the Timp more towards the smoother, comfortable, and cushioned side. It is definitely the most versatile Altra trail shoe right now, and should appeal to both Altra and non-Altra trail runners alike. The effort to improve the fit is welcome and the shoe felt very secure on my foot, uphill and downhill and my toes were free to roam as they should in an ALTRA. The fit actually feels a bit better than say the Lone Peak 5 because the Toe Box is still a little narrower. Mike P (10): A very close comp. They are very similar in the plush feel of the upper as well as cushioned feel underfoot, especially at the forefoot. I think EGO MAX is a better foam though - it feels more lively while Nike’s React and Air unit feels just as soft, but a bit dull in its response. The TK is slightly lighter, but the difference is not felt. Both offer similar levels of traction, but I find the TK’s lug orientation feels intrusive underfoot. I prefer the Timp.The Lone Peak 4.5's fit slightly narrower compared to the Timp 2.0's in the upper. Width of the soles are the same (as it's with all the Altra shoes). How COROS Co-Founder, Lewis Wu, and World Greatest Mountain Athlete, Kilian Jornet, Began a New Chapter. Fast forward a season and the Timp 2 felt a bit off, particularly in regards to sizing, which was noticeably narrower and shorter than the previous version. The midsole had a nice update and the outsole traction remained the same, but the overall feel just wasn’t quite right. That’s why we were excited to find that revisions to this spring’s Timp 3 focus primarily on the fit of the upper, which is very similar to the old-school sizing we first admired. That’s the nutshell review of the Timp 3. If you loved the original, you’ll definitely love this new version. Hoka Challenger: These are 5mm heel to forefoot with a more pointed toe box. They are available in two widths. Here I a link to some more information:

More cushioning underfoot, feels more protective on rougher terrain than the previous Timp(s). Still, it doesn’t feel like “a lot of shoe,” something most Altra fans will likely be happy about Shannon Topo MT-3: A similar shaped toe box to Altra. 3mm heel to forefoot drop. A much firmer more responsive ride. There are flex grooves throughout to complement the midsole’s stiffness for a smooth ride. The zero-drop platform encourages midfoot striking – which also helps smoothen the ride out.

Altra Men's Timp

I am not sure if it was the zero heel-to-toe offset, the type of midsole foam, or the weight of the rubber underneath, but these shoes seemed to hinder my run rather than help it. Superb traction

This was my main beef with the Timp 1.5's, and it certainly is improved in Timp 2.0, but Lone Peak 4.5's are still a little bit superior in this department. The shoe remains comfy and spacious even when the foot starts to swell after long miles of running.Scarpa Goldengate: These are 6mm from heel to forefoot. The toe box is quite broad but not as rounded as an Altra shoe. Here is our review:

The Quantic midsole is as soft and bouncy as it was in the Timp 2 so the Timp 3 feels very comfortable and smooth on tarmac. Perfect for a road to trail shoe that you want to perform well on both a variety of trail and road. The Maxtrax outsole gives a good grip on most trail surfaces. As with all outsoles of this type they aren’t going to get you round your local cross country but, then your cross country shoes wouldn’t be comfortable in a 10km road race. The Timp 3 has the ability to be serviceable on a variety of surfaces. The consequence of this change in the upper design is an increase in weight from 281g to 311g in the TIMP 3.After 10 plus runs on a variety of terrain, pavement, trails, gravel, and mulch, the Timp 3 has held up well. Still a pretty incredible trail shoe for mountain running, just maybe not as good as the last version Topo MT 3: These are 3mm from heel to forefoot and have a more responsive feel to the cushioning. The toe box is rounded like the Timp 4 designed to allow you feet he room to spread on impact. Here is our review: https://www.northernrunner.com/blog/topo-athletic-mt3-review/ Timp 4 upper wraps more over the sides of the foot, contributing to a slipper like feel. Also more upper material, looser in the front, MTN Racer 2 with very thin tongue does give some lace pressure across top of foot] Now let's talk about some other relatively minor things to consider.
