I'm gearing up to start riding and have been trying on boots at a local shop. I noticed the socks they sell there are thick - really thick. Are thick socks better for riding? I tried on some Gaerne SG-10 boots, which was a mistake, since I had not planned on spending that much money. The 8's fit perfect with regular athletic socks, but I'll probably go with a 9 if the thick socks are best. Thanks in advance for your help.
