Rated 3 out of 5Â by Drib Runs big
My son wears a size 3 shoe. I ordered a size 2/3 and they were more like a size 5. I recommend ordering a size down. Also, I don't think these would be very comfortable to wear for a long time or walking a long time as the grooves are harder than I thought they would be. I thought they'd be more squishy.
