Nice quality... exactly as shown.
The socks are very bright and colourful. I like the quality, it is soft and not “rigid” so to say... as for the size, I am not sure if it will be good for European size 43, it might be a bit tight (I bought it for my husband)... I suppose that sizes 37 to 40 will be the best way fitting... because I like it on my feet size 36 and I feel comfortable (personally I like socks to fit loosely) ...
