My first pair leaked along the rubber seam . I sent them back to Bramwell international the uk importers and they sent me a new pair . Had these now for three seasons and still going strong. Try oil or dubbing down the sides of the tongue to stop the squeaking .
Had mine for about 2 years now, use them regularly and love them. Because they were a lot of money and the way I am, I clean and dubbin them regularly and this has helped maintain them and I would expect to get another year out of them at least. They are as said above "awesome" particularly in the hills and because they are relatively light I often use them about the farm as well and on certain shoot days. The only criticism I have taken for them is from a stalker in dorset who I was summer woodland stalking with and he reckoned they were insensitive and therefore noisy underfoot and wellies would have been better. Probably true but not a real issue when wellies are readily available.
Not had any problems with mine. They've been excellent. The Meindl sport wax is far far better stuff than dubbin or Nikwax. You don't need as much and it treats the leather a lot better. Found it on e-bay and certainly wouldn't go back to using Nikwax.
