This shoe has a robust clamping mechanism that grips the flash foot to securely hold most hotshoe based flash units .
This shoe has a 1 ⁄ 4 inch - 20 TPI threaded hole to attach directly to a tripod, or the brass inserts (spigots) provided on many umbrella adapters (see inset). It can also be mounted on many off camera brackets.
The center of the shoe has a "valley" like feature that allows the contacts on the flash foot to sit above the bottom of the shoe (see inset). The flash contacts just dangle in air and touch nothing.
This shoe works very well with almost any flash foot, and is particularly well suited to secure the newer Nikon SB flash units (SB-80, 600, 700, 800, and 900) that have fit issues with other styles of flash shoes.
