@FarFrame Those shoes are Merrell MOAB3s, I think, but I also run in ASIC GT2000s; if you scroll back through the videos you'll see those even working on ice. I'm not a particularly fast runner, and I pay close attention to the surface I'm on. A lot of it comes to feel. I'd say try whatever shoes you have handy that have good treads on them, start off walking and pick up the pace as you go.
