I love these Teva shoes, wish they sold exact shoe in other colors Without that tool lying around I would have had a really hard time getting these on. Although they are very thin they may help to keep it in your ear if they do fall out but this will be marginal due to thinness of the material. Update:It took me almost 3 months in 2017 until I got the replacement (under a warranty). This is a heavy duty item and at the price I paid for it I am certainly getting my moneys worth and then some. I wanted a pulley kit that came with a rope attachment and a straight bar attachment. It actually fit perfect and the clear strap is actually able to form to your foot comfortably! Doesnt fit perfectly and doesnt glow at all. Thank you Teva. The right side had screw holes that were different sizes than the left screw holes.
