Show one's complicated Alpine footwear
I believe the answer is:
snowshoe
'alpine footwear' is the definition.
'snowshoe' can be an answer for 'footwear' (I have seen 'Polar footwear' mean 'snowshoe' so perhaps 'footwear' could also mean 'snowshoe'). I'm not certain of the 'alpine' bit.
'show one's complicated' is the wordplay.
'complicated' is an anagram indicator (a complex or confusing ordering of the letters).
'show'+'ones'='showones'
'showones' is an anagram of 'SNOWSHOE'.
Can you help me to learn more?
(Other definitions for snowshoe that I've seen before include "Winter walking attachment" , "Type of rabbit" , "Aid to Arctic walking" , "Boot worn on a cold surface" , "Polar footwear" .)
