Prior posts on the performance of this shoe have detailed:
I have now taken a pair of Sense to their end of life (EOL).
After about 1200 km (700 miles) the shoes are just now showing evidence of breakdown- peeling of the outsole, diminished cushioning, and lug wear. Although still suitable for road running (as a racing flat), their use on trails has come to an end. This is mainly because the peeling outsole presents a potential tripping hazard, which, at my age, is something worth avoiding. Secondarily, the diminished cushioning is resulting in skeletal wear otherwise not previously apparent on longer (35+ km (20+ miles)) runs. They are still fine on shorter runs as far as I can tell.
I must say that I am pleasantly surprised with how durable and comfortable these shoes have been. With initial reports indicating that they should likely last only about 500 km (300 miles), getting in excess of 1200 km (700 miles) out of this pair is reassuring and clearly justifies the price just based on durability, let alone the excellent on-trail performance documented in earlier posts. I should think that I could get perhaps even more use if I was able to securely re-glue the outsole back to the last- at least for shorter runs. The uppers remain entirely intact with no signs of failing any time soon.
Every time I ran in these shoes as part of a rotation with the Fellcross, I ran about 15-30 seconds faster per km. Not sure why, but certainly the light weight plays a role, however I think that the endofit and the low profile (both from the thickness of the midsole and the height of the lugs) just make me a more efficient forefoot striker.
Salomon S Lab Sense Ultra
Salomon have, this past summer, introduced the Salomon S Lab Sense Ultra- a slightly “beefed-up” version of the Sense. According to reports, the shoe incorporates a bit more rock protection with a thicker “Profeel” film element and a bit more cushioning and traction with deeper lugs (and perhaps a bit more wear). The shoe is slightly heavier, although it is still very light at about 200-210 gms (7-7.5 oz) depending on size. I look forward to this shoe as I think that it will perform better for longer runs and races where the Sense may not provide enough cushion for some runners. Here is a short video of the Sense Ultra:
Well, I have taken the Salomon S Lab Sense from the box to retirement including about 1200 km of running on trails in the Rocky Mountains, racing in two ultramarathons, and used in virtually all expected conditions. The shoes have performed at the highest level in all respects except in the area of cushioning. I confidently recommend the shoes for mountain trail ultramarathon running training and for shorter (<70 km) ultramarathon races. If the S Lab Sense Ultra provides more cushion it may be the right balance between weight and performance. Stay tuned.
