The 10 Seconds 3810 Ultra Arch Support Insoles feature a semi-rigid arch support in addition to a combination arch + metatarsal cushioned pad that runs from the base of the heel all the way through the metatarsals. The result is a heavily cushioned insole that provides firm arch and metatarsal support alongside a deep heel cup and plenty of shock-absorbing padding. For those looking for solid arch support and plenty of cushioning, the Ultra Arch Support insoles are an excellent choice. Description: The tops of the insoles are covered in a fabric top cover that will reduce foot friction to help prevent blisters, wick away moisture to keep your feet dry, and control odors. The body of the insole features thick foam padding for heel-to-toe cushioning, while Poron heel and ball-of-foot cushions absorb impact shock where your feet need it the most. The three-part support system focuses on providing a deep heel cup, semi-rigid arch support, and raised arch + metatarsal cushion, all of which will keep the foot properly supported and aligned for maximum stability and pressure relief. Notes: The arch + metatarsal cushion isn't a traditional metatarsal pad. It runs all the way from the base of the heel through the metatarsals, providing additional arch support & cushioning in additional to metatarsal padding.
