In reply to David Cowley: Not directly relevant to the post, but after my 6th pair of scarpa Zens, my Mescalitos arrived this afternoon Haven't tried them out yet, but the tongue looks like it will let a lot of water in from wet long grass etc But, like my non gtx zens, will be much cooler than any gtx shoe.
Best of all though, the mescalitos were £76 from Bergzeit. No hassles with delivery
