Vibram

These are great for outdoor sports like bouldering, kayaking and running. This is because they give you the sensitivity that your feet need to carry out the sport to the best of your ability whilst providing protection for your feet. They are also good for building up strength in your feet and lower legs because they encourage you to use more muscles to balance yourself than traditional shoes. They are becoming very popular, partly because the well known author Tim Ferris has been seen fashioning them.
