Altra Lone Peak 4.0 vs 4.5

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.

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

• 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.

• 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.
