These makers are using a sizing convention that is no longer common because it is confusing. The Black LWBs are an 11D and the brown are an 10.5D. The first number in both corresponds to the width. The first number is a 4, which is a D. A, B, C, D, E would be 1, 2, 3, 4 and 5 respectively. The last number will be a 0 or 5 representing the half size. 110 would be 11. the 105 would be 10.5. So, 4110 is an 11.0D and 4105 is a 10.5D.
