I haven't heard of them but be careful. Many of these places that sell shoes that can be customized mean they'll let you pick fabrics and colors but they don't really change the foot size. Truly customized shoes are costly because they aren't built on an assembly line or with standard materials. They have to be specially made and they have to be made by people who know what they are doing.
Now...if they are truly custom, brilliant. I went to Argentina and had many pairs of shoes custom made for me. They were as expensive as the DanceNaturals and I love them too...of course those are Tango shoes and aren't suitable to dance ballroom hence...the DanceNaturals. By the way they couldn't fit better if they were custom. The materials...still blow me away. The leather in the shoes is straight sexy.
