Wow, first of all, what an amazing value!  For $20 shipped with free returns, I figured they would feel thin and cheap.  Frankly, I'm kind of stunned by how much these rock.  (Detailed review below.)

I am normally a solid size 8, and fortunately I listened to other reviewers and got the 7.5; which fits PERFECT.  My search for the ideal all-around shoe is darn close with these (I wanted lace-up booties, but can't find that and everything else on my long "must-have" list below):

-2.5" heel that is sturdy but not chunky.  It's a tapered cone-shape, so they're stylish, but I can still run around town without wincing in pain.  Extra bonus points for the completely fabulous rubber tread on the sole.
-Round toe box with no pinching or rubbing on the toes.  This is usually the #1 reason most of my shoes never leave the closet. I have wide-ish feet and bunions, but no problem with these.
-Padded footbed:  Okay, there's a decent amount; nothing like Clarks, but there's lots of room for insoles if needed.
-Stylish: These are an interesting blend of vintage/classic/trendy/retro without looking matronly, which we do NOT want.  With the right above-the-knee pencil skirt and some gray tights, these look very trendy/slightly hot in in an understated way, which we DO want.  The perforated detail, wing-tip design, and buckled strap across the vamp are all really cute up-close.  They don't look cheap at all, the material is soft and feels exactly like leather.  (Looks exactly like the picture.)

Seriously, I would have paid $100 for these shoes.  They look and feel worth it.  I hope this helps you in your purchasing decision.
