Wiggle toes here -- it may help footwear problem (8)
I believe the answer is:
shoetree
'it may help footwear problem' is the definition.
'wiggle toes here' is the wordplay.
'wiggle' indicates an anagram.
'toes'+'here'='toeshere'
'toeshere' with letters rearranged gives 'SHOETREE'.
(Other definitions for shoetree that I've seen before include "what's found in Oxford?" , "It preserves the shape of footwear" , "Device put into footwear to maintain shape" , "A shaped block for holding footwear" , "Device to keep footwear in good shape" .)
