Let me start by saying I love Alegria shoes.  The insole in their shoes are amazing, they are made of a material that molds and conforms to the shape of your foot over time.  That makes them perfect for people with foot pain related to super high arches, which is a problem I suffer from.  Alegria shoes saw me through 3 years of plantar fasciitis before it finally cleared up.

This particular pair of Alegria shoes is well made but is a tad loose in the heel for me.  The mary jane style over the top of the foot secures the shoe well using velcro and is adjustable.  But I am not able to make it tight enough to prevent my foot from slipping up over my narrow heel.  You might need a pair of heel inserts to make it fit you but if you have wide feet you might have less trouble than I did.
