Teva illum Flip Flops with LED
Backpacker says they are “made with the outdoor enthusiast in mind–massaging footbeds, illuminating LED lights, sturdy straps, and rock-solid arch support are just some of their sporty features.” They give the weight as 12.4 ounces for a woman’s size 8 (why do they always choose small size). I’m guessing maybe 15 ounces for the men’s version. It’s worth looking at. After injuring my achilles on a 10-mile first day backpack on  California’s Lost Coast because of poorly broken in boots, a alternative pair of shoes can be important.
Be light. Be safe. Be one with the pack.
I just did a four-day hike in the Trinity Alps of northern California. Sure would have loved a lighter pack, but I did take a cheap pair of flip flops for around the campsite.
I’d be interested in a very lightweight pair of sandles that I could actually hike with in a pinch.
For a while I tried using surf booties because they are warm and light. But at some point I decided they were too heavy … I might go back and check the weight.
I like the LED light on these. I would love to have a pair of these just to have when walking in the streams on my summer hikes.
