Tsukihoshi shoes are the best shoes for kids.  I have bought over 10 pairs for my two kids.  They love Tsukihoshi shoes because they are so comfortable and light.  They are expensive compared to other sneakers.  Because kids grow out so fast, I went cheap and ordered a pair from another manufacture.  My 6 year old son was excited because it (cheap on Tsukihoshi shoes) LOOKED very cool.  Once he tried them on, he immediately said "I don't like it"  I ended up returning the pair and paid twice as much for Tsukihoshi shoes.  When the Tsukihoshi shoes arrived, my son tried them on and he was very happy.  Yes, tsukihoshi shoes run a bit longer.  If you need a pair for your child to wear now, order one or half size down.  Otherwise, order the size that he or she wears now and wait for your child to grow into it.  Highly recommended as always!
