I use Hokas - and love them. I always ran in Vibrams - never in any "real" shoe and all was fine. When I decided to do Comrades, I decided the increased mileage might be a problem and so I should use a cushioned shoe for some of the training and for the race itself. As DV had raved about Hokas, I decided to try them. They were fantastic. I continued in both Hokas and Vibrams, but found that my feet always felt better after a Hoka run than a Vibram run, so gradually I used them more and more. As I came from a zero drop shoe, 4mm is no big deal to me.
I occasionally use vibrams still, but 90% of my running is in Hokas. I used the Bondi (max cushioning) for last year's Comrades, but I have used the Clifton for everything else including this year's Comrades. I did try the Conquest and they were awful.
Its important for me to say, that unlike others, I don't believe in orthotics, or corrective shoes, or someone "analyzing" my gait and suggesting shoes. I think everyone can run in a neutral show just fine.
A few friends have since started running in Hokas - and they all love them and have stayed in them - including one sub-3 marathoner
We went to Lion Sands - it's adjacent to Kruger in the Sabi Sands reserve. I've been to various parks in that area - all superb, as is Kruger. If I had young kids with me I'd go to Kruger for sure, as the huge expense of a private park is wasted on young kids. Kruger is always fantastic.
