ultralight backpacking

I've been wearing Xero shoes as my preferred every day shoe and my hiking shoe of choice for a while. I got a few pairs on a steep sale and now my last pair is starting to die.

I don't mind getting more, but I'd like to see what else is out there. I used to wear Altra and I've gotten Hobbart shoes, but those were weird shaped and rubbed on my pinky toes.

Any suggestions for foot shaped shoes? I'd prefer some cushion like Altras and bonus if there's a business casual looking variety

Last night I tried out a pair of Alpha Direct booties that I made. The low temp was 32F, 0C, and I was under an apex quilt rated for 30F. The booties were very warm and comfortable. The booties replace a thick pair of wool socks which I would usually use to keep my feet warm.

The design was a simple rectangle, folded over and sewn to make a tube, with the end sewn shut. I did not try to shape the booties into a foot shape, they are just a straight cylinder. The length is from the outstretched foot (toes) to the bottom of the knee. The width is the circumference of the calf plus an ample amount (50%) to create a loose fitting sock-like bag that fits over the lower leg. I inserted a thin elastic cord tied with a light tension to hold the top of the bootie above the calf.

The booties were very warm and comfortable, far better than a thick wool sock.
