I've owned the 1494, suede chukka in tan for a few years now. I really love them. The standard 149X chukka is unlined, leydon last and has the flexwelt sole. It makes for a sleek, lightweight shoe that I find perfect for air travel. They are easy to don/doff for TSA and are super light and comfortable.
I was considering adding the snuff version when I came across the J. Crew makeup. It differed in that it was a Barrie last and had a crepe sole. I took a chance and ordered them. Obviously the barrie last is much less sleek but I wanted to try the crepe sole. I thought it would be more versatile for wet weather at my destination and more like a desert boot. The big surprise upon receipt is that are lined. That was a big disappointment. The unlined chukka makes it slipper-like in its comfort. The fact that it was lined wasn't a deal breaker but certainly disappointing.
I was on the fence and considered a return but after a week wearing them indoors I decided that I'd keep them. In the end, for a rubber soled suede chukka, there may be better options than this makeup. However, given that I was ordering online the fact that I know my sizes in Alden was a factor compared to unknown in a different make.
For reference, here a couple of pics to compared the two. Note the difference in length between the tan leydon (11D) and the snuff barrie (10.5). I was also surprised at the wear on that leather piece on the toe portion of the sole. I've read others here that were shocked at how quickly it wears (i.e., Roy boot). I'm not sure if it will have an impact, but it's worth mentioning.
