So some people will definitely balk at this, but the NFB canes totally changed my traveling.
If you're not familiar, the National Federation of the Blind canes are made from either carbon fiber or fiber glass. Instead of being the standard black, white, and red, they are all white from handle to tip.
Additionally, the tips are made from chrome, so they won't glide quite the same way. Instead of sweeping it from side to side, you use what's called the open palm technique. That's gonna be very hard to describe via text, but I'll try.
Basically, you're gonna hold your cane in the palm of your hand with your palm facing the ceiling. Then, you'll move your cane from side to side by opening and closing your hand. This is supposed to reduce the strain on your wrists, preventing fun things like carpel tunnel. It's very similar to the two-point touch technique, and you can definitely use that one if the open palm feels too strange to you at first.
I like the NFB canes because they're just a solid white and don't look so much like a medical device. They're also the lightest canes I've ever used, and since I've switched, I am never going back.
If you're interested in trying one, you can get a rigid, i.e. non-folding cane for free
$1.
If you find you like them, NFB also sells a folding cane and a telescopic one, too. The telescopic ones are great when you have to open your cane on a crowded bus or train.
I hope that helps.
