I'm replacing a pair that I've owned and used all summer every year for 12 years.  I had new heels attached a year ago but I can't find anybody to replace the strap Velcro so I've given up. If it wasn't for that I'd wear these for at least 20 more years (I'll be 90 then).<br /><br />Some people may want glue-on orthotic in the fore-foot...I did 12 years ago..
