My crawling baby is just learning to stand/balance, and I thought getting these for his upcoming baptism would be good, since he could wear them throughout the summer, too. Well, he's in the 18-24m crib shoes from other brands, and I took a wild guess at 6.5 for these, and ended up way overshooting. They were enormous! So, unfortunately, if it's your first pair of stride rites, hit the store for a measurement. If you've bought the brand before and know what size to get, these are actually cute and ride the line between casual/dressy for a baby. I will probably revisit this style of shoe when I know what size to get.
