In reply to Mountain Llama:
Hokas are a great choice if you want to get back into running after injury. They certainly don't make you invincible, so proceed with caution, but they're as cushioned as they come.
Stinson ATR's are exceptional but, as someone suggested, they take a while to get used to running in, predominantly due to sole height.
The Challenger ATR, which is the trail version of their Clifton road shoe, could be a good compromise as it's a bit more conventional.
I've run in Hokas for years and I think they're great shoes, particularly for ultras, but they do have their limitations when it comes to terrain. The soles, even on the trail shoes, are rubbish and offer very little grip on wet grass and mud and on very uneven surfaces and trail, ankle turn can be a problem, which is why I also choose Inov-8s for fell and sketchy trail terrain.
On hard packed trail, short grass, solid paths, they're great, which means they sound like they could be worth a shot for you at least. Sportshoes.com see to do some pretty good offers on Hokas.
Good luck with your recovery.
