Proto-Lezghian: *sol (~s:-)
Meaning: 1 gullet 2 top (of boot)
Rutul: lɨs 1
Kryz: sɨl 2
Comment: 4th class in both languages. Despite metathesis in Rut., the comparison is quite probable: cf. the external evidence and note that the meanings "gullet, throat" and "top of boot" are sometimes interchangeable (cf., e.g. Lezg. q:uχ meaning both).
