So I tried the Vaporfly and it felt amazing but I don't think it's going to provide the level of stability I need towards the end of a marathon. The Zoom Fly flyknit is a bit more firm but a little too heavy. In the past I've used Asics DS trainer which aren't the lightest but the support is great. I've used version 18 and I'm not keen on the recent updates and I'm hoping to find something a bit lighter.
recommedations?
