Stable arch support: Very thickened, hard, and high-density EVA arch support that lifts your flat feet or adapts to your high arch. When inserted into your shoes, it helps with plantar fasciitis, flat feet, and overpronation. Relieves foot, arch, and heel pain and brings comfort to your feet. Premium materials: Exquisite velvet fabric that is comfortable, breathable, sweat-absorbent, odor-resistant, and wear-resistant. Hard EVA arch support can support your arch and force the foot more evenly. Appropriately, a highly elastic shock absorber is added to the bottom of the heel to effectively absorb shock and reduce heel pressure. Ergonomic design: Designed according to the shape of the human foot. It provides effective arch support of 1.38 inches and reduces plantar fascia hyperextension. Three-point force support distributes force across the sole of the foot. Deep heel cup supports your heels and protects your ankles. The non-slip texture of the sole allows you to walk and run without worrying about the insole slipping inside your shoe. Easy Fit: Easy to use. All you have to do is insert the insoles into your shoes. No need to replace the original insole. No cutting required. You just need to choose the appropriate insole size according to the size chart and your sneaker size. Widely Applicable: It is a 3/4 length insole that fits more easily into your shoes. You can insert it into work boots, casual shoes, athletic shoes, canvas shoes, and sneakers. But it doesn't fit high heels, ballet shoes, or flat shoes. It is very easy to insert and remove.
