If you are used to buying stride rite shoes, I suggest you buy at least a size smaller than the size you normally buy. Prior to purchasing these sandals I read some reviews that said they were too large and others that said they were too small, so I took a chance and ordered my sons size (2.5w) in regular stride rite shoes. The 2.5w were much too large so I decided to exchange them for the 1.5w (shown in the pictures). For an accurate comparison, I think its important to compare the sizes of the same brand of shoes (Stride Rite), so I took pictures of the Stride Rite sandals in comparison to the Stride Rite made2play Arron sneakers. The first picture is the size 1.5w sandals compared to the 1.5w stride rite made2play sneakers (the sandals are noticeably larger). The second picture is the 1.5w sandals with the 2.5w made2play and you can see they are about the same size. However, because my son does not wear socks with the sandals and there is less padding on them, the 1.5w is actually even too large, so I am going with the size 1M in sandals even though he usually wears a 2.5w in the made2play sneakers. Other than the size descrepncies these are very nice sandals.
