Anyone heard of Trimsole Tona trainers?

I'm in desperate need of a new pair of trainers and i found a great deal on Groupon for these. The only problem is i've never heard of them so don't know if they're any good. I don't do any running or things like that, i'm just wanting a bit of spring/cushion so that my back doesn't ache as much after doing workout dvds/brisk walks.

Thanks :)
