Very good. Thank you very much for your detailed report on your buying experience. You're lucky that you got one of the pairs there at the sale, I presume. Nice purchase.
Also cool to hear that you are in favour of barefoot/minimalist running shoes. I've got some five fingers (a bit awkward, and also a bit of a hassle to put on and off), tried the Terraplana Evos in green, but am actually mostly wearing Chucks for training and the occassional running.
Good to hear that the insole is giving good insulation. And I like the look of the rubber sole. But you seem to have the Vibram sole or the rubber one?
Now I have to see if I can get 1/2 sizes. My true size would be a US 10.5. On some site I read that if in doubt one should size down half a size. But that recommendation might have been for a boot without the fur lining.
So if you with 43 find the US 10 quite tight, it would probably be better for me to go with the US 11 as I have more of a 43.5-44 size. I'd rather have shoes a bit too large than too small.
