Hi Lindsay,
Shin splints occur when there is imbalance between the calf and shin muscles. Choosing right running sneakers is a very important so as to prevent shin splint. Your running sneakers should match your foot type so as to get optimal injury prevention and comfort. The most important thing to be considered while buying running sneakers is its arch and shock absorption capacity so as to prevent undue stresses. If accessory insole is required then place it.
