Max event distances for each Altra trail running shoe can pull off without making you feel uncomfortable...

	Miles / km's	Cushion	Bottom line
Olympus 4.0 (Men's - Women's)	75+/120+	High	Best for super long hours of standing, walking, hiking or trail running.	Read Review
Timp 2.0 (Men's - Women's)	75/120	Avg-high	2-in-1 one: Trail running and backpacking.	Read Review
Lone Peak 4.5 (Men's - Women's)	50/80	Avg	Safest bet. Closest you get to a typical running shoe anatomy, versatile.	Read Review
Superior 4.5 (Men's - Women's)	30/50	Avg-low	More of a minimalist, performance shoe.	Read Review
King MT 2.0 (Men's - Women's)	10/16	Low	Really performance oriented pick.

These are only approximate values assuming typical settings. If you think you;

Are heavier than the average person,
Relatively less conditioned for longer runs,
Will mostly be running on trails more rocky than average, etc...

...then always opt for the more cushioned option when in doubt.

Altra Lone Peak 4.5's.

The five upgrades took place going from Lone Peak 4.0 to 4.5:

Improved tow-box durability (the issue with 4.0 is fixed),
New lacing system now allows fine tuning the fit in some subtle ways,
More fitted upper,
Quicker midsole recovery,
Some new extra color options and prettier overall design.

Altra really picked up their design game recently.

This means that going from Lone Peak 4.0 to 4.5, the fit, comfort and durability are improved drastically.

Outsole equips the very same outer structure so-called "MaxTrac", so unlike other updates like Timp 1.5 > Timp 2.0 and Olympus 3.5 > Olympus 4.0, traction isn't impacted with this one.

#A sidenote here: REI's trail running shoe chart is GOOLLDDD. Highly recommend you to check it out before you read any further.

This new Grey/Orange color of Lone Peak 4.5 is really liked by many - including me.

19:33 Canberk
Hi Liz! Hope you're having a great day!
19:33 Liz W.
Hello Canberk!
19:33 Liz W.
I am! How about you?
19:34 Canberk
Good, thanks!
19:34 Canberk
I'm wondering about the changes took place going from Lone Peak 4.0 to 4.5. Could you help me about that?
19:34 Liz W.
I would be glad to help you with that.
19:34 Liz W.
The Lone Peak 4.5 has been trimmed down.
19:35 Canberk
Could you elaborate?
19:36 Liz W.
Of course, makes the shoe more flexible and has have an easier lacing system.
19:37 Liz W.
The midsole also recovers more quickly.
19:38 Canberk
I see.
19:38 Liz W.
Hope that helps!
19:38 Liz W.
Is there anything else I can help you with today?
19:39 Canberk
Is Lone Peak 4.5 more fitted compared to the 4.0?
19:40 Liz W.
Customers have found the shoe to fit more snug.
19:41 Canberk
One last question: What about the durability?
19:42 Liz W.
The shoe is durable for trails.
19:42 Liz W.
This has not changed from the 4 to the 4.5
19:43 Canberk
So I guess the upper construction is the same besides the lacing system?
19:43 Liz W.
The upper material is also trimmed down.
19:44 Canberk
But the material durability is the same I guess.
19:44 Liz W.
That is correct!
19:45 Canberk
Another Rep named Morgan told me that durability was enhanced from 4.0 to 4.5 as well. So are you sure it isn't changed?
19:46 Liz W.
Sorry we did have some issues with toe caps however has been addressed with the 4.5.
19:47 Canberk
So the toe-box durability is higher in 4.5.
19:47 Canberk
OK, I guess that's all then!
19:47 Canberk
What about the traction?
19:48 Liz W.
The traction is the same with the Maxtrac. (A perfect combination of grip, traction and durability that will eat up gnarly terrain like a boss).
19:49 Canberk
Is MaxTrac better than Vibra Mega?
19:50 Liz W.
Virbram is actually better since is also sticky.
