Shame, they're great for winter fishing, you can sit in puddles/ easily return fish and everything. They're perfect for size 9 feet too.
Otherwise it would be a good idea to contact Diver Dave, he now sells refurbished/new waders.
I'll find a link and put it up.
Got to point out that thigh waders are not as popular as they used to be and neoprenes even more so since breathables became available.
I have a small stock of good used waders at the moment, mostly in the larger sizes. These are sold for about 1/2 rrp with a years guarantee, seamsealed and tested and UK delivered. As usual i have all sizes of new waders, these are sold with my usual discounts, free uk delivery, free end of first
