I imagine you're well adapted to them.
I certainly haven't got a license to operate them.
I've fallen more times...And most ungracefully in the process.
It is entirely possible (ask me how I know) to swing forward your leg to pass the crutches and trip over the crutch.
Only one of multiple methods of wiping out.
Snow. Ice. Floor cleaner residues. Including a government facility (post office).
Metal pegs with bent tops to guard garden hose? They can hold a pantleg quite securely while the rest of the pants continue on elsewhere.
Steps. Vs leverage.
Set crutches bottoms near a steps base. Swing forward and tilt over step edge onto steps above as crutches remain in place. Struggle back off the stairs (if you're still conscious) into a position you can try from again.
Try next step with crutches away from step bottom edge.
Knock snow/rain/mud off crutches by banging thier feet together? My you're clever.
(Note the worn rivets resulting before they fail and your lower crutch flops outward as you plummet.)
Crutch tip wear indicators? The thumping of landing after a slip works pretty good.
Recent pharmacy going out of business price reductions I nabbed two extra pairs. Left one pair for someone else. Not that I couldn't afford them. I'll be wanting them come winter. I may even fight someone over a pair when mine are slick. And I have searched for replacements when needed. Which mysteriously prevents thier being located. Oh where they should be on a display or shelf at a store or where I put my spares at home. Nope.None here , there . or any where.
Smooth crutch tips are not good in winter. Or slimy boat ramps in the water.
Mr. clever / not satisfied with prematurely breaking worn rivets by banging crutches together ; had to modify crutch tips to use on slippery surfaces. By running screws through them to poke out for traction.
Not as easy as it might seem to the uninitiated. A hole through lower flat disc between crutch tip and crutch is the where to run screw through. Did I mention you need to switch out crutch tips to go on any floor of any value after? Let me rephrase that. Remember, before you remember...To not go on a floor of any value with your weight bearing on metal screw tips. Not so much for your traction as much as your personal safety and others perceptions of you.. Hopping vigorously away from an angry housewife, boat owner, Police officer or similar will be a good cardio effort for you , before you fall down. Again. But that doesn't always mean it's a good thing for your personal well being.
