How about comply foams? http://www.complyfoam.com/premium-earphone-tips/
I have comfort TX series tips in medium, they are the same round size as Shure silicon medium tips. Ordered from there, to Finland.
If it weren't for their overly ridiculous shipping cost. $11 to ship to Sweden. No thanks!
I bought the T-100 from them once but their quality is worse and wear out quicker than the Shure foams.
