I bought these shoes for my 5 year old who is VERY hard on shoes, hoping these would outlast a pair of Nikes I bought him in January and had to already replace by the end of February.  They are very lightweight and flexible.  Love that they can just be pulled on and adjusted to fit with the velcro strap.  They seem to be breathable and don't maintain much moisture, which is good in the AZ heat.  He's only had them for a week and they seem to be holding up well, but definitely look worn.  Not sure if that's from my kid's ability to destroy any shoe or the product. :-)  He says they are very comfortable, and of course, new shoes are always about speed, and they do just fine. At this time, I recommend the product, but they may need some cleaing up around the green areas if you like your shoes to look their best at all times.  Should my son destroy them within the next week or so, I'll let you know as I'm sure there are many parents out there who deal with this dilemna!
