I think someone posted about them recently, but if you’re having issues with impact, maybe have a look at Hoka One One, which use a super thick EVA sole that’s also slightly softer than normal running shoe foam. There’s very little underfoot structure, they rely on the cushioning, and they’ve become really popular with ultra runners because of the increased comfort / jarring reduction.
They’re a bit like the running equivalent of plus-sized tyres in that you lose a lot of trail feel and some precision, but they’re nowhere near as unstable as they look because your foot sinks into the mid-sole and the sole unit is soft enough to deform around smaller irregularities in the trail surface. I don’t like them much off road, but on hard surfaces they work really well for me.
Designed by ex-Salomon French people who spend lots of time in the Alps hammering down steep descents on hardpack trails I think. And yes, they do look weird… 😐
