I've just called littlebarefoot, they said they will have counter in department store (e.g. Sogo) later this month and the price will be higher than bb Expo, maybe $235. Now if we want, we can still buy at Expo price, ie. $220 for one, $200 for two, but they have only a few model left (as many are sold out after Expo).
I've asked them the difference between Jack & Lily, WeeStep and Robeez. They said, Jack & Lily's leather is softer than WeeStep and the shoe is wider than Robeez. Robeez is more expansive but more style.
