Thesae are very good shoes for serious running, well done sketchers (who I would never have looked at previously). In addition to all the positives above, there is one big plus for these - they were the only serious light weight / mid foot running shoes suitable for running in sockless that I could find that are sold in very small sizes, from a 2 up. And available in half sizes - so in addition to the size 2, we have also bought a size 2.5 for later. As they are a great triathlon shoe, these will be used in the UK national triathlon finals (children), in a few weeks, hopefully to good effect
