I wear size 8 normal shoes (Timberlands, dress shoes, gym shoes, everything). I wear size 9 Burton Invader boots. What size should I buy for Kaijus?
I absolutely cannot find a place to try them on in Toronto.
Check if zappos.com has them. They have free return shipping so you can try stuff on.
That way, you could get a size 8 and 9 and try both, and then just return the wrong size.
If zappos doesn't have them, check if the Nike web store has free return shipping. ThirtyTwo did, so maybe they also do for their boots.
If you can get them from dogfunk.com, they'll let you have a free return shipping label for size exchanges.
