Boys Under Armour Shoes- size 4Y-BrAnD NeW

Boys size 4Y Under Armor tennis shoes, grey and neon green/yellow, with brand new no tie "Caterpy" special shoe strings with "bump technology" that hold tension and is supposed to improve foot circulation (also can include the original laces) I bought these for my 9-year-old and he refuses to wear them because he likes slip-ons that don't have shoe strings, he is only ever tried them on in the house, they have never been worn. I paid $80 when purchased. They are brand new Without tags.
