I've had some of the old versions for 8 years. They've had a hammering - both scrambling and as approach shoes while bouldering. They're still in great working order.
My only beef is that I've prefer them to have more grip on the heel, for descending.
I bought a pair on sale when the latest model came out (not sure if that makes them the old, new old, old old or what model) and almost immediately they started coming apart. I returned them and got a refund. I didn't want another pair if that was the quality to be expected.
Also my experience. Utter cobblers (pun intended!)
I won't be touching Tennies (or other Five Ten products) with a barge pole, especially when other brands produce superior products with none or fewer of the downsides.
I can't comment on the difference in climbing ability but in terms of durability: on a five day route on El Cap earlier this year, the rubber on my (brand new) boulder x's had completely worn through on one shoe just where rand joins toe. One partner's (brand new) tennies had completely worn through and had a hole in the toe and the third person's 3 year old ecco work shoes were barely scuffed!
The durability might depend on how they are used. I've seen many people use them as a daytime shoe, crag shoe, house slipper, scrambler and pretty much everything. If I wore one shoe for it all then it wouldn't take long to wear them out. I've had a pair for a year and use them on scrambly hikes and approaches and so far they are great.
Or they could just be crap.
That stealth sole wears out quick, bought a pair in spring, soles are now slick, bald as a coot. But as the article says, great for scrambling and low grade climbs.
Does anyone know if you can get them resoled?
Worst footwear I've ever bought these. I was in the states when my approach shoes fell apart so had no choice. It was either these or some not so rugged looking sportiva ones. Considering the dessert approaches I chose these. Massive mistake. They are so uncomfortable that it just felt like I was walking around in climbing shoes. And the sole started to look worn after about 2 days of owning them.
> ...and don't expect them to last very long. Mine haven't been very durable (unlike the old ones which lasted well).
It's interesting that a few people have mentioned this. There must be/have been a problem judging by the comments. I've just had a look at them again. There isn't really any signs of wear beyond what you'd expect from a shoe that I've had for a year. In fact they look in pretty good nick, although I don't use them as an every day run around shoe.
