@edge , what size are those spikes ?
... i just saved some to my ebay cart and will buy them in a week or so ( ceramic ones ) . I guessed 7mm would be the closest, having just looked at my asics , but maybe 5mm , not sure . I'm gunna try out the 'christmas tree' style instead of the 'pyramid' style because the pyramids look like they'd be useless once they wear down a bit ( too broad a surface to still be a spike ) whereas the christmas trees look like even if they wore down a fair bit it would still be spike like .
Anyway edge , thanks for rekindling my interest in this .... i did look into it , then got put off by 'what if they don't fit /get stuck/snap' etc..... but stuff it , i have old boots i can experiment with and the spikes only cost $12 shipped , so what the hell .
