Question about G502 Hero - 398459

I bought the previous model ages ago - still in top working order! But in the meantime I've been through the foot slides and at first glance they look the same as from this model. Can you order them? I can find them on Amazon from third-party suppliers (e.g. "Mouse Skatez"), but I would have to order them from Germany. I can't find any spare parts from Logitech itself for private customers.
