The Avon Chamois grip is in our opinion the best arthritic golf club grip on the market, by far. How so? It boils down to the ACAS, or 'Air Cushioned Absorption System'.
The ACAS creates a series of 'air pockets' on the inside of the grip which dampen vibration on impact with the golf ball or turf. The reviews show that the Chamois is the best option for a golf grip if you have arthritis, and the soft feel is phenomenal.
Combine these grips with Sting Stopper Inserts, and you have the best possible combination for vibration dampening, and it can add years to your golfing life. To top it off, they are reasonably priced!
