Truthfully, after using Lock Laces, I find most &#34;normal&#34; shoelaces to be an inconvenience.  Shoelaces that come untied (especially while exercising) are bothersome and I prefer not to fasten them with a double knot.  This is my second pair of Lock Laces and I find them to be comfortable and convenient.  They are now a must-have for me whenever I purchase new athletic shoes.
