Just bought a pair of these so will post comments on them later but have used quite a few pairs of Salomon boots in the past and all have been great for comfort.
Mr Explorer it sounds like this make just is not for you no manufacturer has yet made any footwear that fits and feels comfortable for everyone when they are mass produced.
If they leak they probably have a fault be it in the stitching or the gortex lining or the wearer thinking they can wade 2 foot plus deep water in them.
The tread not being great is down to what you use them for and expect them to do and how you walk in them but if not enough grip again this is a good reason to try a different brand, as as there is differences in the rubber compound they use some are softer some have wider spaced lugs etc.
If they are uncomfortable if broken in right you should take them back to the shop most good shops will offer an exchange as they advise you to wear them indoors only for the first week or so as they know there is no magic one fits all boot.
Discuss with them what makes them uncomfortable, are they too narrow? are they crushing or making the arch of your foot sore? etc etc from this info they should be able to direct you to a brand that better covers your foor shape and needs.
I know your post is a couple months old but if you still have the boots stuck in a wardrobe ask the shop if they can accept an exchange first if not advertise them on this site but also still ask the shop first for help deciding what brand and model best suits you.
Good luck.
