Various embodiments of the present disclosure provide a flexible boot for at least partially encompassing an electronic device. In one embodiment, the boot includes a rear panel and a sidewall extending from the real panel. The sidewall includes an inner surface, an outer surface, and a plurality of compressible hollow regions positioned between the inner surface and the outer surface. The rear panel and the inner surface of the sidewall at least partially define a cavity configured to receive the device. Other embodiments of the present disclosure provide a case for housing an electronic device. In one embodiment, the case includes an elastomeric boot and a rigid posterior portion defining an opening therethrough through which a portion of the boot extends. The boot includes a sidewall and is configured to receive the device such that the sidewall at least partially surrounds a plurality of lateral sides of the device.
