Men’s size 12. The Altra Superior 4.5 is designed to handle the most rugged terrain imaginable with many features from Altra. The Gator Traps in the back prevent sand and debris from getting in the shoes, and the tread is built to allow you to float across rocks and bumpy trails. These are in good condition with only mild tread wear usage overall. They’ve been deep cleaned and disinfected by HAND and are ready for their next owner!
