In reply to stormylolol:
hi there,
in true UKC style I think I am about to answer none of your question here, I have a pair of SC4 (that I love) they fit snug but really well and comfortable in my normal 10.5 UK (45 EU).
i realise this is the previous model but I don’t think they have changed sizing that much, funnily enough I am looking to replace mine at the moment, but thinking of moving over to the Speedgoat 4 for better cushioning and the Vibram sole.
hope any of that helps, probably doesn’t, as I am talking about my experiences with a completely different shoe, but hey ho I tried!
you will hopefully get some better answers soon! 😂
