You would think I would remember this from a couple of years ago, but when did you switch from very soft sole shoes, like Robeez, to a still soft but more formed shoe like Stride Rite soft motion shoes?

My 1 year old has just started walking, and her grandfather wants to buy her shoes for Christmas and is waiting for me to tell him exactly what to buy. I had her sized today but I'm wondering if I should go up an extra half size since she should be in Robeez longer... It's also winter, so will be a while before she's walking outside either way.
