Heel Drop

Pronation is part of the natural movement of the human body and refers to the way your foot rolls inward for impact distribution upon landing. Understanding your pronation type can help you find a comfortable running shoe. The GEL-NIMBUS 21 is made for Underpronation and Neutral.
  • Under
  • Neutral
  • Over


  • Foot Type

    High arches
  • Push Off

    The pressure is on smaller toes on outside of foot.
  • How your foot contacts the ground

    The outer side of the heel hits the ground at an increased angle with little or no normal pronation, causing a large transmission of shock through the lower leg.


  • Foot Type

    Normal size arches
  • Push Off

    There is even distribution from the front of the foot.
  • How your foot contacts the ground

    The foot lands on outside of the heel, then rolls inward (pronates) to absorb shock and support body weight.

Rated 1 out of 5 by from Was good for a few months but..... I have been wearing Asics for over 15 years and never had a problem like this. I wore these shoes for a few months and they were perfectly fine then all of a sudden the inside fabric on the heels started to pill. I would go to remove my sock and the heels of sock would be stuck to heel of shoe. Then I started getting bad heel blisters on both feet. Couldn't wear anymore. So I made a warranty claim due to the defect. Asics denied my claim, stating improper fit!!!! Are you kidding me??? I've been the same size 10 for over 15 years. Now I'm looking elsewhere for another brand.

Rated 4 out of 5 by from You definitely want to go a size up This shoe actually runs small so I didn’t get to wear them so I definitely have to return for a bigger size . All my shoes normally or a 6.5 but I’m going to reorder a 7 .

Rated 5 out of 5 by from Shoe fits great for a narrow heel. This shoe is great for a narrow heal fit. You can tie the heel in even tighter by lacing the top two lace holes differently. Lace your shoe as you normally do but leave the last two lace holes on the left unlaced. Thread those last two holes to form a loop on the left by lacing under the lacing hole on the left. Then still on the left and after it comes out the top, lace it down in the last hole. It forms a loop on the left side of the shoe in the last two lacing holes. Do the same looping procedure on the right side of the shoe in the last two lacing holes. Now one at a time, take the leftover shoestrings and thread them through the opposite sides shoe loops and pull. Your heel should fit snugly in your shoe.

Rated 5 out of 5 by from Great shoe Great running shoe. I've been buying this shoe line for years. I'm more of a midfoot to toe runner and I find adequate support in the shoe. I do mostly street running and mild terrain and this shoe works good for that.

Rated 1 out of 5 by from Hurt ! I had bought this shoe before and it fit beautifully. However, the second pair hurt the bones in my feet. I bought them for walking shoes and had to buy another pair of another brand after about two weeks. I'd hoped they would stretch out and not hurt my feet anymore but that wasn't the case. I'm not sure why two pair of the same shoe would fit so differently.
