The only place I've seen the spikeless ones is NikeTown, London Village. They can easily be identified as they are yellow with green accents, as opposed to white with red accents. Also, spikes RRP @ £40, spikeless @ £45. I also seem to remember the intended use of the zoom waffles is indoor track shoes or Walsh alternatives. Theyre not road goers. If memmory serves me correct the NBRC150's are no support road racers. I would recomend the Nike Zoom Vapor if thats what your after (in Nike). Have used it myself before I realised I overpronate (whoops!) and at 165g approx. with a super comfy fit and quite reasonable cushioning, for a racer, its agood road flat. Hope this helps, KK
