Guys seem to finally "come into their own" in Second Life once they have a solid casual look that is both versatile and unified... and that look will depend largely on their footwear. With that in mind, you can hardly do better for a clean, casual look than to invest in a pair of these Sculpted Runners from Redgrave for Men. Made in the style of a modern-generation Puma (check this photo to see what I mean), this shoe is loaded with realistic detail and is very versatile. More than just laces and stitching (both of which are excellent), the texture shading and highlighting show off the muted low-gloss leather surface. To look at them, you can almost feel the material under your fingertips.
I personally recommend them with Redgrave's Dark Blue Jeans or Khaki Cargo Pants and a a beaten leather, suede coat, or sportscoat. Brave souls may try these shoes with a quality suit, as their clean lines and unscuffed surface will keep you looking professional, but they're best shown off when you look like you just pulled them on as you went out the doo. They come in red, white, brown, blue, and black and ring in at L$450 apiece (L$2000 for a fat pack of all five colors). Go grab 'em here: Sculpted Sneakers at Redgrave Men's Fashion
