Well Made
I wear a 9.5 in Merrells, 10 in Nike, and 9 in dress shoes (Ferragamo & E. Zegna). That said, I ordered a 9.5 for these Lowa boots and they're a little small with just cotton socks. I am returning these for a size 10, the size that I wear for Nike sneakers. Overall though, these boots seem really well made...I'm so impressed that I will exchange them for the size 10 and see how it goes. Oh, I also have narrow feet and the Regular width for these feel about right. If you do not have narrow feet, I'd consider the Wide width as suggested by others.

Lowa Renegade Mid GTX
I've had about 3 pairs of Lowa and they've all been fantastic. Comfort right out of the box is known to be great with Lowa. If their last fits your foot you're almost guaranteed a great boot. And they come in Narrow also with some of their styles. The Renegade Mid GTX is a much lighter boot than I've had with Lowa in the past, but I'll be in Africa for quite a while in the desert and wanted a lighter trekking boot. We'll see how well it breathes since it's GTX. Very light and flexible boot with good support. If you are doing some very rocky climbing/hiking these will be too flexible. But for general hiking they're been great so far.

Lowa Comfort
I own 3 pair of Lowa hiking boots. The Renegade are my favorite and I would easily recommend these to others shopping for boots. The Renegade is very comfortable right out of the box. The Vibram soles are superior on these boots. The Vibram soles are significantly better than Lowa's own sole on some of their other boots such as the Zephyr. The Renegade Vibram soles grip better and last longer. The insoles are standard factory issue and will need to be replaced - I use Sole insoles which I find superior to all others. The Renegade runs slightly narrow which fits my foot very well with liners and socks. These boots are waterproof with GORE-TEX which is a must have on the trails I hike. A big plus is the comfort and they are lightweight.

Very good overall
Have used on several car-camping day hikes; performed excellently: very comfortable and light enough for a day hike. Provide very good ankle support for day hike although I am not sure if it would be sufficient for backpacking with weight over 35 to 40 lbs - may want to go with a heavier boot. Otherwise, packing these boots may, for some who desire the option, eliminate the need for camp shoes.

Perfect for backpacking
Took these out for a three day hike in Sequoia early Summer. Put about 20 miles on these shoes through snow melt, snow, backcountry hiking in the snow. Not only did these keep my feet dry and comfortable, they never gave me any blisters or even hot spots. Didnt break them in at all. So far my best pair of boots ever.
