I agree with the other reviewer that these shoes are not that flexible. I do like that they are light-weight. My athletic toddler seems to be a little slower when he's wearing these shoes. I bought so that he could wear something different to the Saucony running shoes he outgrew but yes, I know that these are not running shoes and I shouldn't compare it to same, BUT given that they are made for the kids and we know kids like to run and play, the shoes fall short of my expectations of a good pair of toddler shoes. I think there needs to be some cushioning inside which this shoe badly lacks, and the sole needs to be flexible. There have been a few times when my child tripped on his shoes when running which has never happened with his other saucony shoes. We got the blue pair and it looks cute but I will not buy this shoe again.
