Yes, I'm a fan. I've previously had versions 3 and 4, and whilst the latest one is a little different because it doesn't appear to have the same medial support, it kind of feels like the v3 which were my favourite. I'd say they're a little less stiff than the previous version, but similar level of cushioning, so they feel nice and bouncy, but not spongy. I wear them for everyday training but this includes intervals, tempo, etc.and I'd be tempted to use them for longer races, although I'm happy using lighter shoes for 5k/10k.
The only Lunars I ever tried were LunarGlide but I found them rather clumpy. I think the Zoom Elite are a much smoother, faster feeling ride with good heel to toe transition.
