Probably not - although orthotic devices can help in some cases, like when one leg is shorter than the other. But you do have to be mindful about which shoes you wear. It's better to forget the flip flops and opt for good ankle support because strains in your foot and ankle muscles can throw off your gait and further stress your back.
High heels can aggravate low back pain, partly because - like extra abdominal weight - they can increase lumbar lordosis. It's important that the shoes are cushioned and firm because they absorb more impact than a flimsy pair.
