I will never go back to &#34;regular&#34; laces. I have been using these for 3 months on running shoes & I am incredibly pleased. Lock Laces are high quality, perfect tension-just great. They actually keep better & more even tension than &#34;regular&#34; laces, even if you have been using some form of modified lacing technique with old laces. A tip- after lacing for the first time, don't trim the excess too short, lightly melt tips of laces (to prevent fraying) & don't attach bottom clip-yet. Wear for about 2 weeks to let laces adjust to fit, then do a final trim & attach bottom lock tab.
