The Salomon Sense Ultra shoes that I have reviewed and provided an update for on 17 July 2013 have been sent to the bin. I put on another 260 km (160 miles) since the update when they had about 1200 km (750 miles) of trail wear on a 50% rocky technical/50% buffed single track terrain environment. This gives a total of about 1460 km (907 miles) of wear before failure or US$0.12/km or US$0.20/mile. In my experience this is excellent wear and a reasonable cost per distance metric- particularly given the weight of this shoe.
I retired these shoes because the hole that I documented earlier has grown to such a size that small gravel is now routinely getting into the shoe via this hole and said small gravel is making it’s way under my foot, thereby making running uncomfortable.
The interior of the shoe shows no wear out areas and the cushioning, although not what it was in the first 1000 kms (600 miles), is holding up. I can now feel a bit of discomfort at the tibialis anterior/posterior during and after long (35 km+) runs. If I switch to a newer pair of Sense Ultras this discomfort goes away so I think that the midsole cushioning has reached a critical point in the high use shoes. This critical point seems to be around 1000-1200 km (600-750 miles) for my use and terrain.
The outsole has proven to be remarkably durable with no excessive wear any place on the surface and still plenty of grip after these 1460 kms (907 miles). As a supinator, the outside edges have preferential wear particularly at the heel as I have seen on all of the shoes I have ever worn. Too bad the upper failed as I expect I could get many more kms (miles) out of these.
Overall there are no areas, other than the outer portions of the mesh uppers documented above, of the shoe that have exhibited any excessive wear or breakdown/failure. The laces work as well as new and all of the attachment points are intact and in good condition. The increased coverage of the mesh upper with the polymer overlay at the toe seems to have solved the problem with delamination of the polymer overlay that occurred in all of the 2012 Sense shoes that I have used. It also apparent that peeling of the outer, ‘tread’ portions of the outsole has been resolved as well as neither these shoes nor a second pair have exhibited any such peeling.
I suggest here that increasing the area of the polymer overlay over the area of the mesh uppers that has failed would likely resolve this issue. This area sees a significant amount of trailside abrasives (rocks, plants, etc.) and a bit more protection should go a long way to increasing the life of the uppers.
A great, light weight, high durability, low drop, very comfortable shoe which can take on just about any terrain with confidence. Highly recommended.
