Dont wear worth a crap. The Keens are not as attractive to me, but the upper shoe material is more of a nylon base covered in thick canvas cloth, and will definitely hold up longer than the Grations. Qualidade de som: Sou bem leiga quanto a isso. Buttons IMO feel similar to Finalmouse Air58. I am GI Joe with these boots on. I have pain if I dont wear a supportive shoes. So far, this pair has passed all of my tests:1) Sound quality is great. Now i have to Fax a Parts Request form that was included in the box, this must happen often if this form was in the box. Unlike the Sony?s- Tranparent/Ambient mode is good! I suppose I would have liked to have had one of the compartment be shallower for screws and smaller parts and have it come in closer to the $20 mark but those are very minor complaints.
