The phrase "most shod" does not have a defined etymology as it is a combination of two separate words.
"Most" is a superlative form of the word "much" or "many", which can be traced back to the Old English word "māst". It has Germanic origins and is related to the German word "meist" and Old Norse word "mest".
On the other hand, "shod" is the past participle of the verb "shoe", which comes from the Middle English word "schone", meaning "to provide or fit with shoes". The Old English equivalent for "shoe" is "scoh". This word has its roots in the Proto-Germanic word "skeuhaz" and is related to the Old Norse word "skór" and the German word "Schuh".
