water shoes (Milton)

hi,
I know it is early in the season, but I'm looking for 3 pairs of water shoes over the next couple of months for summer vacation for my grandkids. color doesn't matter
women: size 7 and 8/9
little boys: size 1

I'm in Milton but can pick up in Oakville, Burlington, west end Mississauga, South end Brampton.

thanks,
