To me, a sensible shoe is one that we can wear all day without wanting to cut our feet off above the ankles. In general that would be a heel under three inches (granted I have worn a few flats that were uncomfortable too!). Shoes under three inches can still be fashionable and fun. Take a look at these darlings from ASOS.
ASOS has a nice range of prices to fit into almost any budget and their shipping is usually free worldwide. Keep an eye on the exchange rates to take advantage of the best prices.
