I bought my Teva sandals for a trip to India several years ago. I wore them with socks on the airplane, walked down busy streets and dusty village paths, and slipped them off each time we stepped inside a church. When I got back home, my feet were tanned, leaving white lines where the straps had covered. Each time I showered, I would glance down at my feet and be reminded of the trip all over again.
And even now, 5 years later, wearing those sandals brings back a flood of memories. And reminds me to pray.
