he was afraid these would not fit, but I got them several sizes too big and they did . Super happy with this simple rack, and the cost cannot be beat! We also have a Bobike Mini front seat, and a Burley trailer. Si bien son de color blanco y se ensucian más fácilmente que cualquier otro color, las zapatillas pueden meterse en la lavadora y quedan impolutas. The top case keeps popping off and it doesnt stick. I?m so disappointed because they weren?t cheap and they are cute and comfortable. My daughter was so disappointed when she heard I was going to return them that she immediately started crying (shes 3 years old). Why isnt this five stars from me?Because the description says HARD shell, and I can definitely compress the case with enough pressure applied. Good product for the price, instructions could have been a little more clear but not bad to install. So set aside at least an hour to do the assembly.
