I am an 8 1/2 reg. shoe, 7 velcro and a 6 1/2 blue slipper. The y are a little narrower than the moccasym, but after a month(when they have lost their edge) they perform the same. I am using them as my indoor shoe at the mo' as venoms are out of the loop 'til April. The blues are fine but don't expect much from the heel. Gains half a size through use...
