I bought two pair - one for me, the bride, another pair for one of my bridesmaids that was pregnant (wanted her to walk safely on my big day).  I mainly needed them to walk on the grass lawn during the ceremony so I didn't sink into the soil.  It worked fine for me and lasted all night.  Unfortunately, the pair for my bridesmaid broke/cracked before the night ended.  She was pregnant so obviously wasn't taking any unsafe, risky steps.  I expected them to last more than one time.
