A set of ergonomic handgrips and arm pads make the use of crutches or other walking assist devices more comfortable and less likely to cause repetitive stress injuries. A metacarpal protrusion of the each handgrip is angled outward at about 5 to 25 degrees from front to back when installed to place the user's wrists at a more ergonomic angle (approximately 15 degrees inward rotation). The metacarpal protrusion produces a substantially flat surface with a downward slope. Each handgrip spreads the load out over the hand of the user eliminating pressure. The handgrips can be fitted on crutches, a walker, a cane, or another walking assist device. The arm pad has a pair of protrusions that produce a recess on the side facing away from a user's chest which engages a user's arm and keeps the crutch top positioned correctly while the crutch is in use by the user.
