A new pair of SPD shoes.
My parents bought this pair of Adidas (the only pair I've ever had) in 1994 and they have seen better days, and have been a size or to too small for the last 11 years (was 15 when I got them).
Along with the pedals, they're actually my most retro piece of kit. They're even purple (sparkly too), although i didn't know that at the time - I'm colour blind...
