I love my speed laces!  I got them for my triathlons and it definitely sped up transitions.  They feel more secure on my feet than normal laces.  The only bummer is that they're not hot pink.  I knew they weren't when I purchased them, but my normal laces were hot hot pink and I loved them.  I will just have to give up the hot pink color choice and settle for a cute pink and more secure shoes and speedier transitions. When put that way the pros FAR outweigh a silly little con.
