I have been wearing these sneakers to do my interval training for a year now and they are wonderful. I actually thought they looked nicer than in the photos and I really appreciated that they are nice and roomy in the front, are very lightweight, and seem incredibly durable. I do wish, however, that there was better traction on them. Definitely don't work out on marble floors or take these hiking.
I am quite disappointed that it doesn't seem this model will be back in stock, I would have loved to purchase another pair.
