A chazan who cannot put his legs close together

Hi,

We have noted that one is supposed to recite the amidah with his legs as close as possible to each other, to mirror the prophet Yechezkel's description of single-legged malachim (Yechezkel 1:7).

One who cannot do this should keep his legs as close to each other as possible, and is qualified to serve as shaliach tzibbur (chazan).

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 5:38:6)

Have a great day,
Mordechai
