Thermal?

I have worn down my last pair en would like to invest in new ones! Money is not leading as these are literally the only shoes I wear every day.

I am often in wet and cold places so thermal seemed the perfect solution for me. However, in my country they only sell the 584 (brown like the 585) or in rustic black.

I am not sure if I'll like the 'dots' on the 584 - they look weird to me, and I'm not sure if grey is my style - I'm not sure whether I should just get the color I want as these will be my constant companions for the next 5 years, or man up and get the thermal.

Is the thermal really worth it?
