The Type A4 gets more simple. A more minimal upper and thinner sole help reduce weight and thus increase speed. Ideal for 5k and 10K road races and if you are an elite runner, it will work for the half marathon. The flatter midsole (4mm difference from heel to toe) also makes this shoe a great option for minimalist runners.

Customer Reviews

Comments: I am in love with this shoe, I use it for everything, track workouts, cross country workouts, long runs...The Whole Sha-bang. I feel that this is the best shoe Saucony is making, far superior then the choppy Kinvara 2's. Also the water drains are great in the summer and spring, but can be annoying in the winter, but I have still been rocking my A4's for over 7 months and they keep on giving. I cannot wait for the A5's to come out in February 2012. For anyone who is looking for a good minimal shoe I suggest starting out with this shoe especially if you appreciate a smooth ride unlike most other minimal shoes *cough* Kinvara 2* *cough*.
From: Joey, Syracuse NY USA

Comments: Honestly I can't believe that Saucony continues to make this shoe. There are holes in the bottom of the shoes which small rocks/pebbles can easily slip into while you're running. While I've never felt the rock while running, I've had to use a needle nose plier after every run to remove them. After time, the holes become larger and larger making it easier for rocks to quickly get in.Do yourself a favor, unless you are running on PERFECT streets or track only, go with something a little more substantial and durable.
From: Joe, Hartsdale, NY USA

Comments: This is an awesome shoe! it has the low heel toe drop i was looking for, as well as a very thin sole! With only 14 mm in the heel, it is a perfect amount. my only complaint is the thin mesh inside the outer mesh on the upper. i prefer just the larger mesh like on the fastwich 4, however this is not a big turnoff. i am 6 ft 150 lbs and run a lot. I have a mid-foot strike and don't wear socks.  i can't wait for the type a5 to come out; they look even better.
From: Brendon, Gi, NY USA

Comments: Coming back for my second pair. These shoes have been fantastic for me. I tend to run my shoes till the point where there's only the insole left between my foot and the ground. This shoes has been incredibly durable for it's weight. Rocks getting stuck in the soles was a nuisance at first but I got over it. Recommended for those looking for a minimal light weight shoe.
From: Michael, Albuquerque, NM, USA

Comments: ABSOLUTELY AWESOME SHOE!, excellent fit with the arch bands holding the tongue in place. low heel drop with great cushioning and the outsole had killer traction for fast road racing! it is one of the best lightweight road racing shoes out currently.
From: Mark, Louisiana

Comments: Love it! it's the best shoe out there, at least for me...
From: E, Charlotte NC, USA

Comments: I've been a barefoot (Vibram) trail runner for over a year now but needed something a tad less minimalist for hard pavement street running, but which nonetheless gave me a similar Vibram feel. After trying on 5 or 6 other pairs, the A4 stood out from the crowd. The breathability is unmatched, with mesh in the uppers and perforated holes in the sole, heel, and toe box. Ridiculously cool shoe to run in ~ like someone turned on the AC ~ and I wear this shoe barefoot. Obviously, whoever designed this shoe designed it with a barefoot runner in mind, as the tongue tag is embossed flush with the fabric, the tongue itself has elastic bands on either side to move up and down with the foot, and two very cool hydro-pockets on either side of the heel at the achilles tendon make for a snugger fit (which is good b/c this shoe runs about half a size large). There are no stitching seams in the shoe whatsoever, so wearing it barefoot is easy, and at 6.5 ounces, you might as well be wearing clouds. (Not recommended for trails b/c of the holes in the sole ~ but for street and track, they're the best I've tried.) Great shoe. Couldn't be more pleased.

Comments: I love these shoes.  I am a CrossFitter and love the feel of them for all workouts.  Slim sole, nice fit, it is like wearing a sock with extra protection.  I am buying my 2nd pair.  I have competed in a Duathlon in these shoes and logged many intervals with these shoes.
From: Mike, Lake Ariel, PA, USA

Comments: Just added these to my rotation for increasing mileage to prepare for the Portland Marathon.  I typically run barefoot, or in VFFs, but was hitting a wall adding mileage.  These shoes are just enough shoe and let me run with my sought after mid-sole strike for the longer runs until I build up more foot strength to get over the 8 mile mark barefoot.
From: Chris, Vancouver, WA, USA

Comments: I had about 5 pair of running shoes in rotation.  Different brands such as nike, new balance and even saucony's.  It wasn't until I switched to the A4's that I found the running shoe for me.  My plantar fascia and pain has disappeared after switching to a zero drop shoe and changing my running style to forefoot running.  I use to be a heel striker.  I typically run 15-30 miles per week.  I did make the transition slowly however starting only with a mile at a time until my calves and achilles were strong enough.  Highly recommend these shoes.  I'll be buying another pair or another zero drop shoe.  The vents on the bottom get clogged up with pebbles easily but not an issue for me.

Comments: Just got them on Thursday, wore them for officiating a swim meet (standing for about 4 hours), great shoes, this morning did a 3 mile on treadmill, they feel excellent. Highly recommend. As close as I can get now to barefoot. Love them.
From: Max, McAllen, TX, USA

Comments: I love this shoe. I just finished an Ironman event and had a slow marathon and this shoe still provided enough support to keep me from injury (by the way I'm 6'6" 185 lbs and used nike lunaracer2 before, this is a much better fit for my foot). All I had to do is run a couple of speed workouts before the race.
From: Peter, Queens, NY, USA

Comments: Were great for my first 5k, with no blisters on an introductory run.  However 3 5-10K runs later and the rubber tread on one of the shoes is all but gone and the design of the shoe allows the foam to press into your feet and feel like stepping on stones even on the smoothest concrete.  The weep holes are great for getting water out, but also letting it in.  The smallest puddle will cause your feet to soak instantly.  They will also collect small stones from most asphalt surfaces and due to the extremely thin sole the stones will feel as if they are stuck into your foot.  Great shoe comfort, but not worth all of the little problems.
From: Lance, Ann Arbor, MI, USA

Comments: I tried these on in my Living Room and sent them back the next day. Not sure why but they caused me to walk on the outside of my foot. I underpronate so maybe the shoes exaggerated that motion.
From: Ben, Summerville, SC, USA

Comments: So far, so good. Really good. The GTA4 has more solid, predictable sole. The 4mm drop allows more of a midfoot strike, much more. I found myself naturally landing lighter and smoother.
