Jake's got it right. The Clymb is legit as a company -- I've ordered from them several times, as I know a lot of other users here have, and I've never heard reports of any problems.
The only downside is that shipping is slow. Somewhere around 3 weeks appears to be "normal" for shipping times, based on my experience. My guess is that the site only acts as a front end for merchandise that is warehoused elsewhere by someone else, and it takes a while for all the back end infrastructure to get things in the mail.
However, I've had good communication with them when I had a question on a product, and the stuff I've gotten has been perfect at great prices.
The main thing I keep the site in my feed for is shoe sales. They are the only place I know of that ever does clearance events on Terra Plana VivoBarefoot shoes, which are my current favorites for pretty much every activity -- from the outdoors to the office. No where else I've seen has ever had the Vivo's more than 20% off. In the last six months, they've had three separate sales at The Clymb with Vivo's 50+% off, which is huge savings on shoes that are $150+.
Anyway, I hope the Hoka's work out for you. In general, I've kept getting more minimalist, and I haven't convinced myself that the Hoka's are worth it, since at this point my wife is starting to make fun of me for having more shoes in my closet than she does ... which is weird, since I'm happiest when I'm barefoot. But after two ACL-surgeries (from playing Ultimate), I've been trying different shoes to see whet is going to work out best for long-term health. Living in a city that's 2 hours from decent trails, most of my time is spent on pretty kind terrain, so the Hoka's would just be overkill, but I'm intrigued by the idea behind them.
For "foot protection" and hauling downhill on rocks, I've got two pairs of the Inov-8 X-Talon 240s that I picked up on clearance that are awesome on dry rock (not so good on wet) and loose dirt. Weighing in at 9oz each (size 10.5), they are my current favorites for really bad conditions that need traction. Otherwise, I'm in VFFs or Vivo's.
