The 'brogue' shoe originated in Ireland, where it was often "constructed using untanned hide with perforations, allowing water to drain when crossing wet terrain such as a bog" according to Wikipeda.
However, most shoes don't have these holes for draining the water out – so in wet environments, your footwear may fill with water. Is there a particular name for the sound they make when you walk?
Squelch is close, but is more related to walking through a bog and the noise you make as you step on the bog, not because of the water in your shoes.

Squelch is exactly the word you're looking for, so don't rule it out! As the link (dictionary.reference.com) gives in definition 4:
Personally, I think the word "splashing" is incorrect. From "splash" I infer a water-on-water sound, whereas a "squelch" is an air-through-water sound.
With regards to the other meaning of squelch, there is unlikely to be any confusion. The "to crush something" meaning is transitive, the "watery noise" meaning is intransitive; hence in any one sentence only one meaning can be interpreted. Additionally the context of "mud" and "shoes" makes the "watery noise" meaning clear.
Both meanings are sufficiently common that very few people would hear "after falling the river my shoes squelched for the rest of the hike" and wonder as to why your shoes were crushing something.
