I've suffered from foot issues since I was a kid.  I've had orthodontic inserts for as long as I remember.  Specifically, I have acute tendinitis in my arches which are high arches. Needless to say, I can rarely go to theme parks or anywhere that requires a lot of standing in lines due to extreme arch pain,  even in my orthotics.  I have long skinny feet as well so shoes are often hard to find that fit well.  I read a lot about the vibram five fingers on various blogs and finally decided to give them a try.

When I first got them I had to work a bit to get them on my feet as they are a bit like putting on gloves.  Once on,  I was able to tighten them to a nice fit for my skinny feet.  I did have to cut about 2.5 inches from the velcro straps so they didn't hang off the side.... I sewed the ends to prevent freying.  I spent several hours with the them on the first few days doing things around the house.  I was surprised that I had very little arch or foot pain. The third day my wife and I went to epcot for their food and wine festival and decided to try these out.  It was a gamble but for the first time in my 36 years,  I was able to walk around all day with little foot discomfort!  I still can't believe it but have worn them all day for each of the following 3 days and I'm absolutely a believer!  The bottom line is that these shoes did what thousands of dollars on podiatry couldn't.

I've heard that most people take a bit longer to get used to these but there was really no transition time for me.  I do use toe separators so maybe that helped but after 7 days,  I can slip them on in seconds just like wearing gloves,  stretching my toes wide.  Something else I should point out is that my toes are normal meaning that my big toe is the longest.  If you have abnormal toes or webbed feet, these may not work out for you  but if you're fortunate to not have those issues,  you must try these especially if you have had foot issues.  I will only wear regular shoes to work or other formal occasions but these are my new permanent shoe.  I will buy a few more pair and use them always.

Sizing:  measure like their website says.  I wear a 47 (12US) but the 46 was what I needed per the website.
