Thanks for the replies.
I tried Sport Bike Track gear first since that's where I purchased a new suit, etc and they confirmed that A* has a nationwide backorder on toe sliders until late Sept at least.
Thanks for the nesba parts email, I tried looking around here for a while and couldn't find the email address to check with them. That address needs to be on a sticky or something so that it's easy to find, or maybe I missed if it was already there.
thanks!
