Just bought a pair of Adidas Beckenbaur trainers from the original factory store for £30,
They had various colours and sizes and sizes, I picked up white with blue stripes. They are showing as £35 online but they are £30 in store.
They also had adidas samba for the same price and Nike running trainer for £25
Got mine from the Frodsham store but it's a national deal. Although I expect stock will differ from store to store.
