While we are well aware that it is July (somewhere in the world outside of fog filled SF) flat boots are an early fall purchase because they sell out fast! Here at SITC we've learned this the hard way (aka still hunting down a pair we wanted 3 years ago)!
If you hit stores now you will find your perfect pair before they're sold out and yes, they will be full price but these are great investment shoes as they are comfortable, classic, beautiful and go with everything... plus, trust us, they won't be around at sale time anyway.
JCrew is offering a great pair (at a great price) in 4 shades (black, brown, tan and grey)
For a more "investment" style, try Lindsay's Lanvin pair (they're a few years old now so check Ebay, your local consignment shop, etc for a bargain)
Loeffler Randal makes shoes that are well made, gorgeous and comfortable.
Flat boots look great with dresses and skirts in "pre-fall" and then add tights for colder weather. They're also great for dressing up an otherwise casual jeans / t-shirt or jeans / sweater combo.
