The tenth sponsor for the Platinum Sombrero 5K is Lock Laces. I am not sure if anyone else has issues keeping their shoes tied while running, but this is a huge problem for me. I just recently discovered this product, and I have not yet used a pair of Lock Laces, but I will be ordering some this week. Basically, these are elastic laces with a locking system that is guaranteed not to come undone. You strap your shoes on and run without the worry or hassle of constantly tying your shoes. Lock Laces donated 10 pairs of laces to be donated to lucky participants of the Platinum Sombrero 5K, as well as offering a free shipping code, KYLEJUDE. This code is active today, and will expire on August 13, 2013. All purchases using the promo code KYLEJUDE will result in 20% of the sale being donated directly to St. Jude.
