You might be lucky and have a fully-equipped mobility store near where you live. And if so it might be worth taking the time to visit one in person and try a few different walkers out to see which one you like best. However depending on your current location or level of mobility this might not be possible. The good news is sites like Amazon have a huge range of walkers designed specifically for the elderly that can be delivered to your door, and many of them come with FREE SHIPPING.
