User Review: La Sportiva M-Kevlar
Materials: kevlar/synthetic leather
Use: pretty much everything
Break-in Period: little to none
Weight: 2lb 14oz
Price Paid: $245
Great boot. Very lightweight for the support it gives. Nice features like locking speed-lacing system. Very comfortable. I tried on other models of La Sportiva (Sierra and Tibet) that didn't fit as well out of the box. Perhaps they would've after breaking in, but who needs breaking in?
If they fit your feet, you can't go wrong -- comfort, support, great soles and good for long hikes, backpacking, crampons, rock scrambling, you name it, it does it. Only negative is that it's not waterproof, though of course, it can be treated.
