Elastic shoe laces are a great way to shave valuable seconds off your transition time. Triathlete Sports carries two basic kinds of elastic laces for your convenience. The first fast lace option allows you to slide your foot into your shoe and then pull a toggle to adjust your shoe's tightness. The other option are Xtenex shoe laces. They feature notches which allow you to adjust the tension of your lace at every eyelet. You are able to set these laces to your preferred specifications before your race. At transition you simply slide your feet in and you are ready to go - no additional adjustments are necessary. Both options are much faster than tying and will eliminate any worries of shoes coming untied during your run.
