MI热靴（Multi Interface Shoe）是索尼公司于2012年9月推出的一种热靴接口，物理上基于ISO518规范[1]，可以触发兼容闪光灯，但同时通过前端附带的金手指提供额外功能，除了配合原厂灯实现TTL功能外，还可以支持麦克风、GPS等与相机交换信息。
MI热靴用于替代索尼之前继承美能达单反系统而获得的i-ISO热靴，为标准冷靴附件，与单点热靴产品提供更好的支持。索尼公司在之后推出的相机与摄像机产品上以此来作为热靴标准配置。
概况
索尼在2005年接收柯尼卡美能达公司相机事业部门，沿用其机型于1988年开始配置使用的iISO热靴。因为物理上与ISO518热靴不兼容，对于通用性附件支持不好，及希望增加新的功能，索尼公司于2012年9月随α99一同，发布了新款的MI热靴（Multi Interface）接口[2]，字面为“多接口热靴”。
