Looking for waterproof trekking/walking boots

Hi- Decathlon is a popular and cheap option, but they pretty much exclusively sell Quechua gear, which in my opinion is not great.

Other option is AS adventure. In brussels they have a store in the Toison D'or shopping gallery (where UGC is). They've a much better range of high end gear.

If you ever have any reason to got to Koln, by the way, you could check out globetrotter.de which is a fantastic outdoor shop.

Have to say ifyou can to Wavre the decathlon thT way is pretty big so you would find a range.
