Stig, if there is any hardware store serving a Japanese community that you have access to, they might have them. If you want the spike type, likely they don't have them. Why don't you pm me with your specifics, and if need be I can get you a pair. Happy to do so. I just bought a new pair today with spikes and a toe protector insert. If I figured the exchange correctly, about 316DKK. I think I would recommend a pair of regular types first, then the spike type if you like them, or as you prefer. The regular type have a toe insert as well, at least one brand does. Different lengths up your leg too, but probably the one with the toe protector is only available to about the bottom of your calf. The ones in the photo have many hooks and loops up the back to fasten. I prefer the velcro strap type across the front, much quicker on and off. Let me know.
