I like my shoes to last at least one year. This has caused me some problems the past couple of months because  bought a pair or rubber boots that had been in storage for some time and they started to deteriorate after only 6 months wear. So I've been walking around with holes in my boots for some time. That's  OK when the ground is frozen but not when it melts. I should point out that in Norway we wear rubber boots almost every day because it rains so often. So, I reckon that I've now had the offending items for about a year so I bought some new ones. As you can see they're made for Vikings so should be strong enough. The boots came with a little booklet of information with the motto "challenging the laws of nature since 1920". One of the pages was about the new rubber compound that is 30% ligher than traditional rubber. The info goes on to say. "That means if you walk 10km , your feet will have lifted around 315kg less than wearing traditional boots". That means that traditional boots must weigh 1050kg!

What they are of course meaning is that you must lift an extra 315g 1000 times or something like that. I just weighed a boot and it's 1kg so a 30% saving in weight is around about 300g. Each step is approximately 1m that's 10,000 steps in 10km so you'd have to lift each boot 10,000. How do they get 315kg? 

I think I will go to the training room this evening and lift 10kg, 100 times then tell everyone tomorrow that I lifted 315kg.
