  • Gel Discrete Heel unit is comprised entirely of a silicone-based gel for responsive shock absorption on impact.
  • Large Forefoot Gel cushioning system uses a silicone based gel that attenuates shock during toe-off.


  • Solyte is an ultra light, top-of-the-line midsole that delivers durable and responsive cushioning.
  • Guidance Line is a vertical flex groove in the forefoot for improved gait efficiency.
  • Propulsion Trusstic System utilizes a thermal plastic unit that connects the lateral heel to the medial forefoot. This unit works to release stored energy and propel you forward during toe-off.

  • Open mesh in the upper keeps feet cool.
  • Personal Heel Fit (PHF) uses a two layer memory foam lining in the heel collar to provide a individualized fit.

Customer Reviews

Comments: Received my new Asic Gel Kinsei 4 shoes yesterday and took them out on a slow paced six mile break-in run. My first impression is that it is one of the most comfortable shoes I've run in yet. This is not a racing shoe, but a good tempo run, training shoe. I have normal arches and do not over or under pronate. It's too early to make a true evaluation, but my first impression is that I'm going to get some enjoyment in running in these. The Running Warehouse is the fastest company I know in getting your order to you. What great service. If I can break away from running I'll update you in a few weeks.
