'FAVOURITES ... BUT NOT SO SURE ABOUT LATEST VERSION'
Strengths: Light enough to race in. Sufficient support for longer training runs and for a marathon, if you're a light problem-free runner. Great hold round the heel, roomy round the toes. Much comfier (for me) than the Asics DS - and much cheaper.
Weaknesses: I tried to buy the exact same online, but they sent me the Elixir 2 update. Still good, but I felt they had a bit more support and pushed my foot outward a bit, blistering my little toe. I thought they felt a bit heavier, but that is a bit unfair, because (I checked) and they're identical in weight. (Still ran a good FLM in the new version - so not too disappointed.)
Overall: If I can spot the Elixir original version still for sale, I'll stock up for the future.
