depends what I am doing, if it is "light" work, like car repairs, woodwork etc, it is a pair of filthy trainers, if it is machining, fabrication or anything concerning equipment heavier than a light hammer, it's on with Lidls best steel toecap work boots, generally get about two years out of a pair, for a lot less than anywhere else. At the moment though I have a pair of dickies work boots, with a fairly high top that protect my ankles, but still fit inside my trousers, so that those evil little blobs of weld spatter dont go down the tops! They are also described as 100% waterproof, which is always a bonus in our great British climate!
