What are some signs of quality in the various types of soft-soled shoes which usually don't feature a raised heel. I figure that since most traditional peoples wear their moccasins or weejuns or kamiks (arctic skin boots) for walking all around the great outdoors, soft soles are the way to go outside of the concrete jungle. But 90% of all shoe manufacturers seem to sell the soft-soled type of footwear for loungewear only, i.e. something you wouldn't wear across the river and through the woods. So I thought someone here might know something about which leather soles hold up the best (I know they'll need replacing eventually). And what can I do to keep a leather sole supple? All shoe product manufacturers talk about how good their cream or wax is for keeping the upper soft and pliable, but surely the same can be done to thin leather soles?
