Leather lining for shoes was made from unfinished and pigment-finished glutaraldehyde-tanned leather and chrome-tanned leather prepared from pig skin. The effect of the different treatments on the heat and moisture transfer properties of the lining leather was investigated at 20℃ and 65％ RH using an apparatus that simulates the microclimate of the shoes. The apparatus was developed by modeling the conditions expected during actual shoe wearing. 　　1. The water absorption, water vapour permeability, water vapour discharge, and thermal conductivity of the unfinished leather tended to be higher than those of the pigment finished leather. 　　2. Under simulated perspiration, the heat flow for the unfinished leather was higher than that for the pigment finished leather. Thus, the temperature and humidity in the apparatus were lower because of faster heat release. In addition, measured thermograms showed that the unfinished leather dried faster than the finished leather due to a rapid increase in the sample surface temperature and due to the heat of adsorption. 　　3. The water absorption, water vapour permeability, thermal conductivity, and heat flow of the unfinished glutaraldehyde-tanned leathers tended to be slightly higher than those of the chrome-tanned leather. 　　Based on the above results, shoes made using unfinished leather linings are expected to be more comfortable because the heat and moisture transfer properties of unfinished leather are better than those of pigment-finished leather.
