Experience podiatrist recommended comfort with the Ergonx Lithium safety work shoe! Designed to reduce arch, heel, and back pain, the Ergonx Lithium lace up safety shoe is dedicated to delivering all-day comfort, and has the additional benefit of being airport friendly as well as being slip, heat, fuel, and oil resistant. The fibreglass composite safety toe works overtime to keep you protected whilst keeping the overall weight of the work shoe to a minimum. A very rigid embedded shank works in conjunction with the arch support insole to relieve Plantar Fasciitis related pain.
