He has 10 pairs of shoes and each pair is made of 2 individual shoes for a total of 10*2 = <<10*2=20>>20 shoes

He has already polished 45% of the 20 individual shoes so he has polished .45*20 = <<45*.01*20=9>>9 shoes

He has 20 shoes and has already polished 9 shoes so he has 20-9 = <<20-9=11>>11 more shoes to polish
