I highly doubt a calf-tear could be caused by "excessive cushioning"
also, I wouldn't think any extra effort needed while wearing cushioned shoes would be that significant
the main thing you need on a long jog/walk is for the shoes to be comfortable full stop. in particular wrt any chance of giving you blisters you just need to try them out on a few longish outings first I'd say if you could do 25 miles with no probs, you'd probably be OK for 40
niggles towards the end (and cramp) would be more likely to be down to lack of fitness rather than shoes
Sorry, been catching up on two weeks worth of stuff (including a puma advert), meant to get back to you sooner.
So current state of things: PM pages have been restored but chronological order within all bookmarks is still an issue.
Notifications is still an on going problem, one that we're having to pick apart step by step. The main issue stems from the confusing follow thread option at the top of threads, the email me when a reply is made button and the automatic function, plus the options in forum settings. The solution will be a simplified version of these or, what I'm pushing for, a new forum platform.
Things that have delayed all this are myself being away, one of the developers has had a baby and the asics 26.2 campaign. These aren't excuses, I'm just telling you how it is regarding resources and man power currently.
so over 3 weeks since last progress report... and over 5 months since probs first started...
