Slightly off topic - though exercise is important to weight loss. I've noticed quite a lot of people here have arthritis and wonder if any of you have advice. I have osteoarthritis in a lot of the small foot joints - I had to give up ice skating because of this, balancing on the edge of a blade creates enormous pressure. But I really want to keep walking good distances. In the summer I walk in startlingly expensive running shoes which give lots of cushioning , and can comfortably manage 7 or 8 miles. They aren't suitable in wet or muddy conditions though and even with Sorbothane insoles in hiking boots I'm in a lot of pain after 4 miles and it still hurts the next day. Does anyone know of any well cushioned waterproof hiking shoes or boots?
