In five months after I bought the Ultra 105, I was shocked to see my outer sole delaminate. I turned it into the store to send the shoes to the warranty department. TNF graciously got me a new pair and it seems like the shoes are more comfortable than before. Unfortunately, it's only 3 weeks when I noticed there are signs of peeling again.
Not sure if this is a global problem for all TNF footwear.
My co-worker had mentioned that he has a friend with a pair of TNF shoes that delaminated in short time as well.
Although I have not worn Ultra 106, by looking at the close up in the photos on the REI site, I noticed the midsole and outer sole has poor craftsmanship as well.
I asked TNF to get me a different model since this one is not working out. But for the 3rd time, I got the Ultra 105 GTX XCR, we'll see if this pair holds up.
