Not sure if it is worth the effort
I am not too sure how I feel about these.  This is great in theory and I love that this pack provides six sets (12 pegs) in the various sizes.  I found that this size pack would be most applicable to most of my shoes, so I would not pick the larger sizes unless your heels are thicker overall.<br /><br />Tip: As soon as the original tip breaks, do not keep walking on them until you replace them! I found that some of my shoes that had broken off continued to flatten the nail and now I cannot get the original nail out in order to replace the tip. My fault!<br /><br />After I pulled out the original peg on a shoe, I found that when I inserted a new tip, it would not stay in. It slips and falls out so incredibly easily.  I measured the nail of the new and old, and they are the same thickness/size so it is not that the nail is smaller.  I am not sure why they won't stay in. I might try to super glue the edge of the plastic to the bottom of the heel while avoiding the nail so that I can replace again if needed.<br /><br />Pulling the nails out are also incredibly difficult. Even for those that are not flattened out, they are stuck in there so well that it takes an awful lot of effort and time to get the old nails out.<br /><br />Great concept, but not sure if it is worth the headaches to do it this way instead of just taking them to a cobbler.
