I have used my Renegades for hiking in mountainous jungle without a trail, spelunking in caves, for cold, wet weather in the city, general day hikes in Upstate NY and keeping my feet safe at rock concerts. They're a little warm/heavy for the tropics, but otherwise, I love these boots. I have a hard-to-fit foot: wide toe, high arch, narrow heel. These boots have enough room in the front without heel slippage in the back. I take a size 9 in street shoes, and the size 9 boots allow enough room for heavy socks. Don't order up a size. The absolute best part is that Lowa boots require no break-in period. No blisters, no stiffness -- they are comfortable right out of the box. I've had mine for three years and they're still just as waterproof as when I got them.
