There are various types. To get the best (most cost-effective) recommendation, you'd need to tell the forum what camera and what studio strobes you plan to connect.
For some combinations, you need an adapter that merely connects the hotshoe terminals to a female PC jack.
For other combinations you will need an adapter that has circuitry in it to reduce the "trigger voltage" from the flash units to a level acceptable to the camera. If your flash unit(s) have a trigger voltage that exceeds the spec for the camera, you can fry (over time in some cases and instantly in others) the device in the camera that triggers the flash.
