I have the woman's pace glove and fell in love with them, so naturally I wanted my boys to have the barefoot shoes as well. My 5 year old fits in the 12s (a little big, they say they run 1/2 size big) but my 3 year old isn't quite fitting in the 10s yet (the smallest size they make so far). My 5 year old loves them, they are the go-to shoe for him and his brother can't wait to fit into his. I highly recommend these!

Great shoes. My son has been wearing KEENS every summer. When he tried these on at REI, he cried when we didn't buy them (at first). Now that we have them, he wont wear his KEENs anymore. He says these are so comfortable. I love that they can get wet, can be washed, are super flexible, and yet have arch support and protect his feet. The bottoms have awesome grip so on the playground equipment, he can climb w/o slipping.
CON: they STINK! I mean STINK! I've washed them several times. However, the lately they have a nasty odor to them that you can smell while he's wearing them. It's a horrible smell and I'm tempted to return them for a new pair. I've washed them several times, tried a few tricks like drying in the sun, stuffing them with dryer sheets, etc. To no avail.
I found a product that deorderizes smelly shoes. I'll try that next. If not, reluctantly they will go back. I sure hope the next pair doesnt smell like this.
It seems I'm the only reviewer with this problem. So, please try them. You'll love the comfort and the fit.

I bought these for my 3 year old anti shoe wearing son in hopes they would be the silver bullet...and guess what?! He loves them, won't take them off. I kid you not! They are the most flexible, lightweight shoes ever and so practical too as they are totally washable. I will say they seem to run about a half size bigger than most, but could be attributed to the nice wide toe box they offer to allow kids toes to spread and feel free. I have since bought my daughter who is 7 a pair as she was so envious and turns out these are the only shoes she'll wear now too. The [$] price tag seemed alot at first, but well worth the price. I just ordered a pair for both myself and husband so we could share in the fun and enjoyment of wearing these shoes.
