This is an awesome thread! I have been a fan of White's boots for a few years and mostly followed/participated in the thread at FL. That thread is almost all SD. I like that this thread has a wider range of White's boots and some deeper info. For everyone's enjoyment, here are a few pics of my beloved SD.
I got them in Feb 2011. They are black cherry water buffalo with the swing last and a 700 half sole. I wasn't in love with the swing last when I first got the boots. It is wide and makes for a substantial look, especially with double-row stitching. But after I broke them in and got it used to it, I like it just fine now. It is definitely a very roomy toe box.
More than anything I think the swing last and double stitching makes for a more casual boot. At first I thought I would wear mine in a business casual setting with khakis and a sportcoat, but I found it didn't work for me. I think the standard last and a close trim is needed for that. So my SDs moved into a "jeans" role. Luckily my dress code at work has moved much more casual and I wear jeans almost every day now.
A month of wear:
A year of wear - you can see that the buffalo takes on a lot of wrinkles and texture. You can also see the thinness of the leather by looking at the tongue. The leather has scuffed rather significantly, but I have also allowed them to patina. The only treatment I give them is an periodic brushing and wiping with Obenauf's. I've never used any polish or cream. I haven't done any actual labor in these boots, but I think the buffalo has stood up well. I have no doubt it will last a long, long time. But as it is a thin leather, I wouldn't recommend it as a true work boot.
After shoveling snow this past winter. It's actually a terrible picture, but shows these boots can take some abuse!
My SDs are very comfortable. I've done an 8mile urban hike on cement and my feet felt great. I've also done 2-3 mile hikes on dirt/grass/mud. They aren't the perfect hiking boot, though. The ankle is too low (not enough support) and the traction on the 700 sole is minimal. But none of that is the boot's fault. I'm close to adding some SJs with 100 soles for that purpose. (Details to follow...this thread really helped me come up the specs I wanted.)
My SDs will remain the perfect casual, around town boot.
