Looks like my trusty old Scarpa boots are past their best after, I'm guessing, about 15 years..... I think those ones were ML55's or something but whatever they were called they were the thick leather model which I think they call 3 season boots because they are a bit toasty in summer. Typical Scottish weather is more the priority so I leaning towards getting the new version of what I had......http://www.gooutdoors.co.uk/scarpa-sl-activ-walking-boot-p189921 . I keep looking at more modern looking materials but can they be trusted to last as long? And yes, I should have cleaned and waxed the leather more often than I did but in my defence sods law dictates that I will always forget to wax them before a holiday and forget to take wax with me. Hmmmm....maybe I should put a spare can of beeswax in with the camping gear I also suspect the raised peat bog I frequent with my dogs doesn't help as it is acidic. And all the crouching for macro shots puts stress on the leather around the ball of my feet so overall I think they've served me well and if I had bought a lesser boot I'd have wanted to replace them long before now. I think I got them around the time I got extension tubes so they have had a fair bit of use anyway. Any thoughts?
