"Turkic boot straps and attached garters" Topic

Adapted from CLOTHING ‘The Saljuqs and the post-Saljuq period by Elsie H. Peck
'A characteristic fashion for rulers and men of high rank in the late 12th and early 13th centuries was tall boots, a natural choice of footgear for nomadic peoples, with a long tradition in Persia, from the Achaemenid period onward. On two ceramic pieces the pointed boot tops are elongated to form straps, which were apparently attached to inner belts in the manner of the leggings worn by the Parthians and Sasanians. That the boots illustrated in the Varqa wa Golšāh manuscript were attached in this way is clear from battle scenes, in which the displacement of the coat reveals a broad thong reaching from the knee to an inner belt. This method of securing boots was certainly of Central Asian origin and is represented in 6th-7th-century sculptures from Fondukistan, and 8th-9th-century wall paintings from Bäzäklik.'

The boot-straps at Fondukistan may also have a ‘garter' attached. Something similar can be seen on A Kipchak Balbal at Luhansk, 11th century & A Kipchak Balbal, 12th century, Hermitage Museum, St. Petersburg, Russia

I am not sure that there are in fact boot-straps or legging-straps on that first Parthian terracotta, the BM one. What is visible on the thigh is surely a "Sarmatian-style" dagger in a four-lobed sheath – see Winkelmann at link abb. VI-VIII.
