Astro turf football boots size 6 (Ilkley LS29)

Is anyone getting shut of their old football boots that still have life left in them my daughter has started playing football on a all weather pitch I said I will get her some boots but want to know that she is not going to decide it’s not for her in a couple of weeks so thought if there is any second hand pairs that would fit she could use them till she decides if she wants to carry on
