Protalus T-100 are full-length insoles for standard volume shoes such as dress shoes and casual shoes. These insoles align the body and support the entire foot, especially the subtalar joint, preventing excess foot motion. This alignment reduces stress on the ankles, knees, and hips.

Protalus T-100 shoe inserts for flat feet are designed with semi-rigid orthotic arch support and feature a patented Tri-Planer technology to optimize the ankle-heel position. The insoles have a top cloth that is anti-bacterial, anti-friction, and moisture-wicking. The EVA foam molded body provides cushioning and comfort and have forefoot and heel padding made of poron for enhanced shock absorption.

However, keep in mind that Protalus shoe inserts for flat feet are not custom-made, and they do not fit quite as well as custom orthotics, making them less effective for flat feet.

Softec insoles are ideal for loose-fitting footwear and activities requiring maximum shock absorption. They help improve balance, reduce plantar fascia strain, and promote equal weight distribution on the feet while eliminating pain, reducing fatigue, and helping to prevent injury.

For a store-bought insole, Softec insoles are fairly effective. Their custom-moldable design gives you all the benefits of personalized support at an affordable cost. However, these simply do not hold up compared to custom orthotics for flat feet that factor in foot pathology.

As Softec insoles are not custom-fitted, they require molding—alternatively, you can wear the footbeds for a few days to allow them to adapt to your feet, but they do seem to take longer to break in.

They come in multiple sizes and arch heights, allowing you to find as close a fit as possible. They are best for shoes with full-length removable inserts and work well for overpronators and those with plantar fasciitis.

However, they do not produce the best results when used to manage flat feet-related pain since they don't allow for the perfect fit.

This cost-effective solution serves as a great alternative to expensive medical-grade orthotics. However, the brand's returns policy only honors returns within 30 days of purchase, and the customer will be responsible for the shipping costs.
