Some classics are marked down, as well as clothing (like the classic Trefoil t-shirts down to just £15) and accessories if you want tho dig deeper. But I’ll focus on the trainers here. The selection there includes the Adidas Country OG down to £33 (from £65), a pair of Rod Laver Vintage at £31 (down from £62), Adidas Topanga at £54 (down from £77) and the Gazelle Indoor with the leather upper at £42 (down from £70.
Much more too if you fancy a browse. You can see them all at the Adidas online store website.
However, note that you can get many of the latest big Adidas releases (like the Island Series reissues) for much-reduced prices in the End Clothing Sale. Perhaps worth checking there first before you buy.
