The word "shodden" may seem like an irregular spelling of "shod," but it actually follows the typical pattern for forming the past participle of verbs ending in "-d." In IPA phonetics, the word is pronounced /ˈʃɑdən/. This means the "sh" sound is followed by the "ah" vowel sound, which is pronounced with an open mouth and relaxed tongue. The "d" sound at the end is pronounced like a soft "n." So, "shodden" simply means "having been shod."
