Spenco puts extra material in both. A thick SpenCore heel pad sits right under the heel strike, and a SpenCore forefoot crash pad cushions the front of the foot. The rest of the insole is Spenco&#8217;s lightweight PolySorb foam.<\/p>\n<p>A deep heel cup keeps the foot centered, and a metatarsal arch support helps take pressure off the ball of the foot. A &#8220;first ray drop zone&#8221; under the big toe joint is designed to allow a more natural push-off. The top cover is low friction to cut down on hot spots and blisters.<\/p>\n<p>The arch support is soft. Spenco designed it for people who want some support without a stiff feel. That makes it comfortable from the first day, with no break-in, but it won&#8217;t correct flat feet or significant overpronation. For that, look at the PowerStep or Superfeet.<\/p>\n<p>It&#8217;s a great pick if you walk a lot on site: long walks between buildings, up and down stairs, or along slab and gravel all day. The heel and forefoot pads take the sting out of every step.<\/p>\n<p>With nearly 7,000 Amazon ratings at around 4.4 stars, it&#8217;s well proven. Note that some listings still use the older PolySorb Heavy Duty name.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Thick heel and forefoot crash pads for maximum shock absorption, with soft arch support.
