I bought 3 pairs of shoes for my daughter; 2 New Balance and this Under Armor, all were girls a size 5.5. The two New Balances fit exactly how we envisioned, the right size with room for trash to grow in. However, Under Armor fits a lot tighter than expected. I am not currently in the US but if I were in the States I would return it and order a size 6 in this shoe. Looks like Under Armor is smaller.
