OK you need to check out Bourne Sports in UK.
they are always selling old model spikes. May not advertise them on their site though - you may need to contact them. Only a couple of years ago they were still advertising adidas sprint ii (white with pink and green stripes) in an addition of athletics weekly - that model was UK size 8.5 for 25 pounds. Pretty sure that's the ones you describe. I agree they were a great spike. I have the accelerator from the same range. The ones flo jo and kingdom used to wear.
