Of course! One of the biggest advantages of Soul Slopz over shoes is that they're more hygienic -- you can wash them every time you wear them, though you'll likely find you don't need to, thanks to a proprietary leather foot saddle that keeps sweat off the bottom of the socks. But I recommend drying them on a line -- the soles will last longer if your Slopz aren't constantly exposed to higher dryer temperatures.
Sure. I wouldn't compete in them, but you can run down the street or across the beach, if the urge arises. Think of Soul Slopz as having a sole that roughly compares with the soles of your flip-flops (but much more securely attached to your feet): there are considerably more stable platforms to take on a jog, but they'll get you from Point A to Point B, lickety-split. After all, some of us were born to run.
Although all Slopz are unisex, they all are listed in men's and women's (American and Euro) to help you find the best fit with the size chart to which you've become accustomed. I use whole sizes only, so if you normally wear a Size 9.5 shoe, go ahead and bump it up to a 10. Soul Slopz will neither bind your toes like shoes nor allow them to slide around if you're a size off either way.
Two, in fact: Knee-high and crew (mid-shin).
Although I don't advise it (see "rough terrain," in the question above), I've done it. Here's what I've told every hiker who has inquired over the last four years: Stash a pair in your backpack. If you're setting up camp at the end of the day, Slopz are ideal for wearing in your sleeping bag, because you can come and go from your tent with ease when nature calls. But even if you're day-hiking, Soul-Slopz are the ideal antidote to those debilitating blisters that form from ill-fitting boots. Remove your boots and continue your trek in Soul Slopz.
This one should probably be at the top, since I get this inquiry 100x more than any of the others. Ilysse is an Old German variant of Alice that means "noble" or "exalted." So is Elise, which is pronounced the same as my name. But my people are from the other side of the English Channel: I'm Irish/Scottish.
