I found a pair of leather boots at topshop that I like with wooden heels, can I dye the leather AND the heel?

I want to dye it black! http://www.topshop.com/webapp/wcs/stores/servlet/ProductDisplay?beginIndex=0&viewAllFlag=&catalogId=33057&storeId=12556&productId=2483478&langId=-1&categoryId=&searchTerm=ambush&pageSize=20
