INTRODUCTION

The Gel Lyte33 is a moderate feature, minimum neutral shoe designed for speed work, racing and daily training.

CUSHIONING

  • Rearfoot Gel cushioning system uses a silicone based gel for responsive shock absorption on impact.

MIDSOLE

  • Solyte is an ultra light, top-of-the-line midsole that delivers durable and responsive cushioning.
  • F.A.S.T. Ride uses a firmer version of Solyte foam for a more responsive ride.
  • Guidance Line is a vertical flex groove in the forefoot for improved gait efficiency.
  • F.A.S.T. Drop 6mm heel-to-toe drop encourages midfoot and forefoot striking.

UPPER

  • Open mesh on the upper provides breathable coverage.
  • F.A.S.T. Heel hugs the heel with minimal materials for a lower weight shoe.
  • Reflectivity contains reflective material allowing runner to be seen in low-light conditions.
  • California Slip Lasting involves stitching the upper along the perimeter of a synthetic material which is then attached to the midsole.

OUTSOLE

  • Asics High Abrasion Rubber (AHAR) in the heel is made of carbon rubber for exceptional durability.
  • F.A.S.T. Sole uses minimal outsole materials only in high-wear areas.

Comments: I had to buy two eventually because it fit me true to size unlike the description. It has been comfortable for running, but i have only used it up to 10k.
From: Asif, Jamaica

Comments: Agreed break-in is required, especially in the first few days and absolutely out of the box.
From: Konstantin, Madison, MS, United States

Comments: Used these shoes for a 10k race out of the box and agree that they do require some break-in time; I could initially feel the upper digging into the top of my toes when the shoe flexed, and the shoe felt extremely firm. After a few weeks of use (both speed work and longer training runs) the shoe is feeling more comfortable, although I am unsure if it has softened up or if I am now just used to the feel. Pros: lightweight, versatile, 6mm heel-toe drop is a comfortable transition from traditional shoes. Cons: break-in required, shoe is narrow (has caused some blistering on the outside of my pinkie toes).
From: Josh, BC, Canada

Comments: These shoes are almost perfect. I felt that they had a longer break-in period than some of my previous trainers, most of which were ds trainers. They took about a week to break into. I run about 75-80 miles per week and these shoes are just starting to break down after 600 miles. Thats 200 more than the recomended 400 mile range. I feel like these shoes encourage a mid to forefoot strike. However, i think they could improve from a lower offset, 2 or 4 millimeters. Hopefully asics would take this off the heel seeing as forefoot strikers dont need cushioning in the heel, or its added weight. Durability is just below average. The spot where the outsole comes up on the toe started to peel after about 300 miles. This is most likely because of the shoe's flexibility and the fact that ahar is usually not used in the forefoot. Durasponge is usually used in the forefoot because it is more cushy and flexible but it wears faster. In this case the tradeoff is worth it because of the increase in outsole durability. The toe thing doesnt effect the performance at all and is barely noticeable. Since this and the possibility of a lower offset are my only two complaints, i would rate these shoes a 4.5 out of 5.

Comments: After my 3rd run in the Lyte's, I must say im pretty impressed with what Asic's has put together. The Lyte's are certainly for a runner looking for a minimalist-like experience. With a 24mm heel and a 18mm toe (6mm h-t drop) and 7.8oz, the Lyte is certainly for a light runner (max 160ish) and for one with good biomechanics. I consider myself a runner with decent biomechanics and they certainly make you change it up. Although very subtle, this shoe is obviously one that a person should change over to slowly (depending on your past shoe history acourse). My last shoes were the Nike Flex Runs and I occasionally wore my Nike Free's (5.0's v3) and I feel like the Lyte's are a combination if you will between the two. Slightly stiff out of the box, the Lyte's will certainly take some getting used to, but with a great weight, and a shoe that offers structured cushioning, it definitely strikes a great balance between minimalism and modern. I am: 18, neutral/slight pronation, 140lb, 50-65mpw

Comments: Quite simply one of the best shoes I have ever owned. This shoe went above and beyond my expectations and has held up to 70+ mile weeks. I have had them for over a year now and they have finally broken down. I'm planning on ordering another pair especially for this great price. They're not only suited for asphalt but work exceptionally well on trails (limestone gravel, wood chips, grass), tracks, and treadmills, making it the perfect running shoe. If these shoes have held up to my rigorous training, abuse, and use of these shoes then I would most certainly recommend them to anyone. They're very well stable yet light enough to be doing speed work in track workouts. They also allow for a comfortable distance run. I did not experience one injury in the timeframe that I wore and ran in these shoes. So go buy a pair!!!

Comments: I've worn a number of minimal shoes in the past year from other shoe companies.  Prior to this I wore nothing but Asics.  I was pleased to see these come out and made my purchase a week before a 1/2 IM.  They are a tad stiffer than the Kinvarna's but other than that the fit was very comfortable.  I did a short 2 mile warm up and then decided to use them for the 1/2 marathon portion of the IM.  I had no issues, kept a decent cadence and experienced no hot spots that several other reviewers have experienced.  While there is always room for improvement I'm very happy with the Lytes.  Well done Asics.
From: Steve, Janesville, WI  USA

Comments: I must say these are the worst shoes I have worn in my life - they are narrow and run long.  They did very strange things to my stride and my feet hurt all over.  The Asics do not come close to the Saucony Kinvara which I have had 3 pairs of and I am running back too immediately.

From: Todd, Breckenridge, co

Comments: Alternating between these and the Kinvara 3 on longer runs.  It's definitely in that sweet spot between too minimal and too much shoe.  Light and responsive, but a little stiffer than the Kinvara.  The sizing recs ("Fits large, purchase 1/2 size smaller than standard running shoe size") were pretty accurate, though mine felt a tad tight.  Swapping out the insole for a thinner one helped a bunch.  Ditto on the other review on the heat issue.  Not a very breathable shoe.  
3.5 out of 5.
From: Anonymous 

Comments: overall i liked these shoes. I did a 6 mile wear test.
Pro's
Very quiet and efficient to run in. The shoe also felt very stable on slightly uneven surfaces.
Con's
My feet tended to start to generate a bit of heat after about 4 miles. I got this similar sensation when wear testing the nike free shoes that seem to have a similar sole. The amount of heat was a bit lower than the nike shoes and it was a warm texas night. I did not sweat it was not a problem.I started to feel a crease right below where the foremost shoelace hole is on one side. This was from the outer glossy layer.
Overall i give it a 4 out of 5, the upper still has a little room for improvement. i also think a slightly firmer forefoot may reduce the heat issue i experienced.
From: Gordon, Katy, Texas, USA

Comments: Great shoe once you break them in!  These hit the sweet spot for me for minimalist trainers.  I was looking for a little more shoe than my usual Hyperspeed 4's for everyday training and these definitely fit the bill.
From: Anonymous

Comments: I run 100-120 miles a week and i absolutely love these shoes.  I love Asics and it is about time the accommodated to a more minimalist runner.  I have my minimalist trainers but i won't wear them on long runs.  There is enough shoe with the lyte 33 to get me through a 30 mile long run.  The only thing i wish was different is a 4mm offset over 6 but i am not complaining.
