ÂŁ42.95

The Trio Easy Fit Orthotic Insole is a premium 3/4-length orthotic designed specifically for slimmer-fitting footwear, including office shoes, smart shoes and everyday casual footwear.

Finding an orthotic that fits comfortably into slimmer footwear can often be difficult. The Trio Easy Fit Orthotic Insole has been carefully selected by Mark Smith Orthotics to provide dependable heel and arch support in a slim 3/4-length design, making it ideal for office shoes, smart footwear and everyday shoes where internal space is limited.

Unlike a full-length insole, the Trio Easy Fit supports the heel and arch while leaving the forefoot free, helping maintain valuable space inside the front of the shoe without compromising everyday comfort and support.

Available in Medium or Firm densities and adult sizes from UK 3 to UK 12, the Trio Easy Fit allows you to choose the combination that best suits your footwear, comfort preferences and daily activities.

Whether you're working in an office, attending formal events or simply wearing slimmer everyday footwear, the Trio Easy Fit provides dependable support backed by decades of orthotic expertise.
