When you buy boots, do you buy boots that are the same size as your regular shoe size or do you buy a size bigger?

The same size! Boots tend to have more room than shoes anyway.

"Bigger" .... as I use my boots for motorcycle riding and always wear two pairs of socks.

No that was your choice. I always buy one sixe bigger so when I puton think wool socks on they real confortable

My boots are the same size as the rest of my shoes, but I have no problem with that cos I don't wear socks inside them.

1/2 size bigger than regular shoe size. Is it still in good condition? You may want to ask around anyone u know who have slightly bigger shoe size than u and who fit better. You can sell it over ebay. In this way, you can use the money and buy the size 8 1/2 boots.

I usually by a bigger size in boots than my shoe size .

i go with 1/2 size bigger

I tend to buy a half size larger, but that's only because I wear the hell out of boots and I don't expect to replace them for years.
