These Salomon Uma Trois boots are light!  They're sleek and appealing.  I'm looking forward to wearing them and will report back as we age together ... the rains, cooler temps are coming and they'll be tested with romps around San Francisco and about the peninsula.  I did take the advice of other reviewers and order up a half size and am happy I did; normally I wear an 8.5 but ordered the 9 and cannot imagine anything less.  Be patient with zipping up on less than slender calves such as mine, but know you can ... just be patient, zip it you will.  By the way, another reviewer mentioned her boots' visible gluing between rubber toe, base and the thinsulite (sp?) material but I do not. These are light, sleek and easy to wear!
