- Take it easy
Train your feet to walk barefoot. Don’t start with too long walks. Not only that you hurt your feet, you could also get blisters while walking (vibram five fingers classic).
- Wet feet getting colder much faster
Don’t let them get wet, and your feet are getting colder even faster. They could stay cold.
- Sun heats you up
It’s better to walk in the sun. Your body temperature get’s warmer as well as the feet.
- Avoid walking on concrete
My walks on concrete were awful so far. Maybe it’s a training thing, maybe not. I’d rather avoid it.
- Minimum temperature
If the outside temperature is colder than 9°C, your feet are getting colder much faster which you can’t compensate with warm clothes covering the body. Though the rubber sole isolates very good between the foot and the icy ground.
If you’re up for hiking, be sure you practices enough before. You should be aware that you can cut your feet at sharp things (not from the sole – from the top). Check if not poisonous animals can cause problems (e.g. Australia).
