I've heard a fair few complaints about Bullson boots, but I have a pair and so far so good *touches wood* Mine are the ones with that close with Velcro. They've always been completely waterproof and very comfy,. They've given the needed protection when I had an off, only had a blue toe nail to show for it. Recently they are letting in a bit of moisture when it rains heavily, I think a good clean and a polish will sort that out. I've had them for more than a year and short of some £300 Daytona boots I haven't found any other boots that fit so well and would do the job. That said, if I had two pairs with issues like you did I'd also want a refund, having to return things for replacement is a waste of the precious little free time I have nowadays.
