The only actual sign of unwanted wear is on the shoe laces. The metal eyelet, which is third down, clearly wears the laces thin. Either this or the laces just aren’t as tough as the rest of the boot. Still, for me, this is a very small fault. Laces are cheap and are way, way easier to replace than a whole new boot. I think the wearing of these laces is testament to how ‘through the mill’ the boots have been taken. When you compare that level of wear on the laces to how good the boots are still looking, I think it reflects very well on the build quality of CAT boots. While the outside guards against sudden downpours, the inside of CAT Sire boots is all about comfort. The designers have added microfibre synthetic linings so that the boots feel soft and welcoming despite their rugged construction. The EASE midsole also supports feet perfectly, preventing strain over long periods. Durable and Safe So that’s the end of the comparison photos and I hope you’ve gleamed a little bit about how these boots are wearing – which is very well. I haven’t actually mentioned my favourite feature of the Sire boots: what they’re like to wear. They are light for a boot as rugged looking as them and because of their well designed EASE Footbed and EASE Midsole, they’re extremely comfortable. I’ve warn these shoes through many 12+ hour days. I’ve been wearing them to work and still want to wear them when I go out after getting home. With the incredible power of the internet and my amazing technological prowess, I have managed to create the images below – When you hover your mouse over these photographs they will magically change from what the CAT Sire Waterproof Boots looked like straight out of the box, to what they look like today. Go ahead and marvel at both the strikingly cool-looking boots and my Bill Gates beating ICT skills.
