Turns out they werent wide enough for my feet. I ended.up returning them. Ended up needing orthotics made for my feet. I guess product looked good but didnt seem much different than what I could buy at my local store.

I have had a pair of PolySorb Cross Trainer insoles for a couple of years. I use the same pair in all my sneakers. Because these insoles are affordable, I decided to get two more pairs so I could leave them in my shoes.

I have used these for many years in both my running shoes and hiking boots and have found them to be extremely comfortable. I have tried many inserts, including orthotics, and these are the best for my needs.

I have been using spenco cross trainer insoles for years. I use them in ALL my shoes. Nike stores sales people didn't give me info about if they were going to still be selling them there (my size was not available) and the selection was very small. I have never had a foot problem I just like Spenco because they are the real deal (cushiony). MABY THAT'S WHY I DON'T HAVE A FOOT PROBLEM CAUSE I'VE BEEN WEARING THESE CROSS TRAINER INSOLES FOREVER.

These are great. Have been using them for last 5 years. They help my feet and legs feel better. Also my tennis shoes fit better. Thanks Spenco

The Cross trainer is good for atheletics. I appreciate the Quality of the product It seems that - so far- in my 5 years of using Spenco products that Spenco is one of the few shoe accessory Company's that has not taken Away From its ' Quality' and type of materials they use. Ill keep purchasing Spenco products till it begins to downgrade its quality:)

My husband uses these inserts in his tennis sneakers. They were recommended by his podiatrist. He is happy with the comfort that he is provided with them.

It's been years since my feet didn't hurt. My new podiatrist told me about Spenco and suggested I get some Cross Trainers. The first day with them in my shoes I was in disbelief... my feet did not hurt! I've now gone weeks without my feet hurting! I'll never wear shoes again without Spenco Cross Trainers!

I use this amazing product for the last 15+years and it is by far one of the best in that field. I used to be sale man and I was on my feet 10-14 hours a day and that product made my day much easier. I had a pair that made special for me and paid few hundred dollars for it and it didn't do the job. I see myself using this product for many years to come.

Excellent comfort and relief from ongoing callous problem with feet. Highly recommend this product

Ordered due to some foot problems. Had 2-3 weeks of relief then they became worn out. Now I am right back to the same pain again. Will not buy anymore.

Needed extra padding for my heel due to cancer surgery. These inserts really did the trick

Impressed 11 months ago

Great with or without socks. Nice support throughout, and a nice snug hug on the top of my shoes. This has helped alleviate stinging and aging pain in my heel resulting from pronation and dry skin almost immediately.

Great insoles that last a long time and make all athletic shoes and boots feel great

For the past 10 years I have been purchasing your wonderful innersoles at the shopping mall. This year when I went to purchase a new set they were out. So I decided to contact Spenco directly. The sales associates were extremely helpful and found the price even cheaper than at the mall. Definitely would recommend them for everyone. I take all of the innersoles out of my regular shoes and put these Spenco cross trainers in. I even wear them in my house slippers!

I Have been using this item for several years and find it very helpful in preventing hurting feet.

kathywenski 1 years ago

I've used my new insoles for just a week, but they seem to cushion my foot well; for my feet, the heel pad is a bit too bulky, as I need only added forefoot cushion. I had to buy larger size shoes to avoid cramping my foot.

icecreamboy 1 years ago

These insoles are the best. I've Paid $50 for other insoles but they are not as good as these.

Twinsborg 1 years ago

I have had feet problems off and on most of my adult life. I have been to foot doctors and have had professional orthotics made. I have tried dr shoals and soft sole and many others. I got my first pair of these around 20 years ago and I still have them. I just bought 4 new pair and the old ones are almost as good as the new ones. These always get my feet back to felling pain free. Thanks, Frank

I am recovering (5 months post) from foot surgery. I have a ligament still hurting very bad on the inside of my foot. I've tried all of the in-store shoe inserts and nothing helped. I was very skeptical about these, even though my doctor recommended them. They couldn't be better than the ones at the store that I 'was measured by a machine' for and didn't work ... they are much cheaper. I was so wrong. These have been lifesavers for me. I highly recommend them.

An article recommended this product for those with plantar fasciitis. I tried it in a couple of different shoes and it was OK but not as comfortable as another insert I have been using. The arch support was not sufficient for my needs.

Simply put, the best. I have been buying these insoles for years. They keep my feet comfortable during anything I do for activity and I have not been bothered by the heel spurs I used to get before I bought the PolySorb Cross Trainer Insoles.

Skurthe 1 years ago

I bought these inserts because of a recommendation from my physical therapist and i love them. The only issue is that i bought a second pair for my work shoes and i feel like the style/ amount of insole changed. Other than that, I am very satisfied with them!

Diana Diaz 1 years ago

I have had planters fasciitis for well over 1year, I was told to buy the spenco cross trainer support, aside from the regular trearment, I have virtually no pain in my foot, these supports are a God send I thought I would never have relief. These are the best!!!

Sandy 1 years ago

I didn't buy these for myself, I purchased them for my 4ft7in 80 year old mother!! (size 0 insole) She has suffered from plantar facisitis for over 2 decades and purchased a multitude of expensive custom made orthotics . Last year I convinced her to change podiatrist, Viola! hands her Spenco Crossfit Insoles. Now less frequent bouts of foot pain, and no more expensive orthotic. Much Thanks

I was recommended this product by my physical therapist and I really love it. I feel that it helps correct my posture and arch. Easy process to buy and ship and I received the product quickly.

I am a nurse and I am on my feet 12 hours a day or more. I finally have relief from the tired and achy feet and legs. I also got a pair for my s.o. and he loves them as well.

Always worth every penny.

Even thought I purchased good shoes for my gym class my heel was still hurting by the end of class. I replaced the original insoles with this Spenco insole and now have no more heel pain from my plantar fasciitis! The insoles fit and feel great!

Dorothy 2 years ago

I've had many operations on my toes and foot problems over the years. My podiatrist recommended these and they are great. My feet feel better and more comfortable to walk on. Keep up the good product/s.

Bill Epter 2 years ago

This is my 3rd set of these inserts and have not experienced an injury when using them. My first contact with Spenco was when I purchased a bike seat cover for an English racing bike...provided excellent comfort on top of the narrow leather seat. When looking for running shoes that would provide maximum comfort (over $100), I asked the sales person if there was anything I could do to further increase the shoe's cushioning. He said replace the insole with Spenco insoles. Rather than buy the shoes, I went home and ordered the insoles for about $20 and placed them in my shoes...Excellent! In fact, if I'm not using running shoes just to walk around in, I replace ALL of the insoles in ALL of my running shoes...

cushions all areas on the bottom of the foot that might be tender. Has a nice arch support and cupped heel. Next best thing to the Spencon Total support insole that I use for my Plantar Faciitis

dr 3 years ago

the cross trainers have given me very good cushioning in my heels. Even after playing tennis, my feet/heels are not sore and tender. I wear the cross trainer in my work shoes as well. These are a very supportive product.

no more sore foot 3 years ago

I had suffered from such bad heal pain that each day was nothing but a torture. I had special orthotics made but the pain did not go away. I changed podiatrist and he suggested I try the Spenco Cross Trainer and so I did. In less than two weeks the pain was gone. I truly can not imagine living with out this product and i'm grateful every day I put my shoes on!

Excellent product, repeat user!

Wally 3 years ago

I have Dupuytren's Contracture, a condition that contracts "cords" in my feet, making it painful to walk on anything firm. The PolySorb Cross Trainer inserts allow me to wear shoes pain free. I'm so happy they were recommended by my doctor.

Mark 3 years ago

My podiatrist recommended these inserts to limit the formation of painful calluses on the bottoms of my feet. They fit nicely in my FootJoy DryJoy golf shoes when the factory inserts are removed. So far I like the feel of the inserts.

George 3 years ago

I purchased 3 pairs of Spenco Inserts for my shoes about 1 month ago. They have worked great. I have a bunion on the right side of my right foot, and the Inserts have relieved the pain so now I can walk and exercise with ease. Try them, they're great.

I just wanted to tell you what an awesome insole you make. I work for Home Depot and I am on my feet on a concrete floor for 10 hrs. I've gotten $200 orthotics but I always take them out and go back to your insoles. Way to go. A product I can trust.

twiggied 3 years ago

The only complaint I have is that I could not order them in my exact size but other than that they are great! Thank you Spenco!

TerryFranklin29 3 years ago

I would recommend this product for individuals who need more support than typically comes in shoes.

Nancy 3 years ago

I wear the PolySorb Cross Trainer inserts in all my shoes. After trying other brands and types of varying costs, I have found these are by far the best and most comfortable inserts. They are reasonably priced and never seem to wear out.

I have been using your insole for many years now. I have liked it since day one buying from Footlocker. Thank you for providing such a great item.
