there is nothing on these boots to indicate their actual size but my husbands shoes size is about an 11.5. i have measured the bottom of the entire boot (if that helps!) and they are 34cm long. these come with a bag for storage. there is a sticker on the back of each boot that says '360' - not sure what that relates to. if you happen to live in/around the lower north shore in sydney you are welcome to come try them on. please not i only accept payment via paypal or cash on delivery. contact needs to be made within 3 days and the item MUST be collected/paid for within 7. if you have any questions, please let me know. thanks!
