one more time...the odhin is not just a taller abyss. they are different boots that share the same perforated sole, but almost nothing else. we had a new pair of each on our recent 21 day trip and i was surprised to see how different they were. neither model held up real well, and i returned my pair for a refund.

i would not buy another pair at retail but did buy another pair at $70. the credit card receipt does not indicate that they charged shipping, a pleasant surprise, if true.

if your travels include a lot of lining/tracking, more rugged portages, or if you just feel you need more ankle support, get the odhin. if not, the abyss will do.

i do not view the otb boot as a cold water boot. you may feel the need for a neoprene sock early or late in the season. if so, buy the correct size.
