I really don't know why I have not used these thingies before - they are a lifesaver to me. I'm at that age that bending is getting really difficult so having to lean down to tie my shoelaces sometimes become problematic. Now that I "discovered" Lock Laces, I'm changing all my regular shoelaces to these things.
I have just ordered 2 more of these to match my other shoes.

First off, after watching the video on how to put these on, I did just that.
Just to clarify, there is nothing wrong with Lock Laces, these are MY problems.
Problem #1: The first loop at the top of the shoe near the toes are very small and very hard to thread the lock laces in it and also through the first 2 holes. So I put the shoes on my lap and threaded them that way. Then I put on the shoes and finish threading the laces per instructions.
Problem #2: I guess I don't have strength to press the cord clip together (even using both hands) that I had to use a pair of pliers to do that.
Problem #3: After I have closed the cord clip, I noticed that I forgot to thread the laces thru the last loop. So I took a flat head screwdriver and forced open the clip and I was able to do that without breaking the clip.
Problem #4: After I had trimmed the laces and I had worn the shoes to the gym and had to readjust the laces, I found that the laces were too long. I was going to leave them like that but every time I look down, I just could not stand it. So I took my flat head screwdriver again to open the clip (and again I did not break them) and cut them shorter - singed the ends with a candle lighter and even put a dab of glue just to be sure.
I really don't know if opening and locking the cord clips more than 2 times is recommended - probably not! So I hope that the next lock laces I put on my shoes will go over more smoothly than this first time! At least I'm sure it will, I think!

Thank you Lock Laces and Amazon!
