On the website, there is a list of sizes with the length of the shoe given in inches. Whitney is currently wearing a size 3 (5 inches) with her sure steps and this is a perfect fit!!! Whitney would most likely wear a size 2 without sure steps (she still fits into a cute pair of baby crib shoes from gap that are labeled size 6-12 months!) and her foot measures 4 inches almost exactly. So for her, the 3s were big when we got them, even with the sure steps but now they fit perfectly. I have also ordered 2 pairs of size 4s but they are still too big even with her sure steps. I couldn't help myself - I also ordered a pair of size 5s for when her feet grow even more - how could I pass up 1/2 off. By the way - the code for 1/2 off is SALE and the sale ends on October 15th!
If you are thinking about ordering any Bugaboos for your older children - Anne is 4 years old and we have two pair of size 9s. According to the size list a 9 is 7 1/2 inches long. Anne's foot measures just over 6 inches (almost 6 1/4 inches) - so with socks a 9 fits with a little bit of room to grow. I also ordered a size 10 but it is way too big at this point in time - hopefully in the spring they will fit :) Hope this helps!!!
