Since I lack time, I shop online quite a lot. And when it comes to shoes, I like going on sarenza.com. You really need to rummage around, because they don't always have the greatest selection, but the search is very focused , and they have lots of fun brands, so I always find what I want. I recently bought a pair of Bensimon trainers in Liberty print for the entire family.
The added plus: the good deal area when you can buy shoes for four kids.
