We present an analysis of high proper motion objects that we have found in arecent study and in this work with multi-epoch astrometry from the Wide-fieldInfrared Survey Explorer (WISE). Using photometry and proper motions from 2MASSand WISE, we have identified the members of this sample that are likely to belate type, nearby, or metal poor. We have performed optical and near-infraredspectroscopy on 41 objects, from which we measure spectral types that rangefrom M4-T2.5. This sample includes 11 blue L dwarfs and five subdwarfs; thelatter were also classified as such in the recent study by Kirkpatrick andcoworkers. Based on their spectral types and photometry, several of ourspectroscopic targets may have distances of <20 pc with the closest at ~12 pc.The tangential velocities implied by the spectrophotometric distances andproper motions indicate that four of the five subdwarfs are probably members ofthe Galactic halo while several other objects, including the early-T dwarf WISEJ210529.08-623558.7, may belong to the thick disk.
