Re: Software testing?
I do wonder if spending less than £80 in a cheaper shop for new pair would be a better option.
I would recommend starting with a different brand of expensive boot.
My experience is that until the last time I changed shoes/boots, the durability of my footwear was more or less independent of the price I paid. It seriously didn't seem to matter what brand I bought or how much I paid. In six to nine months they would be knackered in one way or another.
Then the local centre commercial (it's not an indoor shopping centre, nor a shopping mall, because it's in France, sorry) had a temporary Timberland stand just before Christmas 2015. I needed to replace the latest footwear disaster, so I dropped 220 euros on a pair of "plain" Timberland boots.
More than two years later, they are still going strong. The water-resist is a bit the worse for wear, and I will soon need to replace the (original) laces, but after two years of walking a bit more than seven kilometres a day(1), five days a week, I have not had to do *anything* even vaguely related to maintenance on them.
(1) That figure is based on the results of carrying a Wii Fit U "Fit Meter" pedometer, and comparative measurements by GPS suggest that the true figure is closer to 9km per day.
