These shoes are excellent right out of the box. I am military and run every day. Shoes have handled every terrain I have thrown at them. The shoes even made it through my dog (dutch shepherd) after leaving her home for too long one day.
These shoes converted me to Salomon. Though I've run in shoes from Oregon based companies, Maryland based companies and two Japanese companies, these French headquartered, Finnish owned wonders are awesome for every type of running that I do. I've run on roads, trails and tough mudders with these shoes and they remain a staple in my running 'drobe. The fact that I took them on a tough mudder and was able to wash them back to life and still use the drawstring showed me their durability and quality. These are all-around running shoes and though not waterproof, they are much more durable than other shoes I've used.
I really like the feel of these shoes. I use them mostly for cross-training at a gym. The fit runs about a 1/4 size small in my opinion but that was easy to fix thanks to Moosejaws rockin return policy. Comfort is primo in these. I have a mid to high volume foot with a low arch and average width. as for durability and construction, there are some cosmetic issues. the stitching around the tongue is loose (I think these were the first or last on the thread bobbin). Ive seen plenty of these shoes that had no issues in that regard. Bottom line, these are great shoes for the money. I scored mine on sale here at MJ. I'll get another pair.
