## Questions & Answers

**Q: Is this the same arch support that has a 2r on the black side under spenco?**
A: On the underside mine has a 3r and 3L. The 3 or 2 is the length size and the r & L is for right and left feet. I do like these arch supports. Have wore them for years.

**Q: Are the insoles washable?**
A: Yes, just like your sneaker shoes. They recommend soapy water, but you can also throw them in the washing machine too.

**Q: Why does the spenco rx orthotic arch support full length insoles, men's 12-13.5, list $29.99 with $15.00/count? (if you do not know do not answer)**
A: It is to refer that the product comes in pairs (1right + 1left), that means 2 units in one box. Some orthotic products are sold separately, just right or just let. I hope my answer helps you.

**Q: The pic shows a 4r. how can i purchase a 5r?**
A: We have 3 in stock......size 5 is for 12-13 size shoe.
You would still have to order through Amazon.
I checked listing and it is available

### ⭐⭐⭐⭐⭐ Great solution for plantar fasciitis pain
*by L***. on January 4, 2026*

ABSOLUTELY FANTASTIC!! Recommended by my doctor, it solved my plantar fasciitis. I'm ordering more, and putting them in my everyday shoes, work shoes, and house shoes. Very well made, and have lasted over a year so far.

### ⭐⭐⭐⭐⭐ Very Good Arch Supports And A Great Value
*by M***Y on October 20, 2025*

I have some really high arches, so orthotics are an absolute must for me. I've tried a lot of different arch supports, including some pretty expensive ones, and I keep coming back to these.

### ⭐⭐⭐⭐ Insole size does not fit perfectly
*by L***O on December 21, 2021*

These insoles were recommended by my podiatrist due to my plantar fasciitis and I immediately purchased them without hesitation. I just got this pair of insoles less than a month ago and I am still trying them whenever I run errands like going to the grocery store because at the moment per my podiatrist I should not be doing any walking or running exercises. There is something good about these insoles but at the moment is difficult for me to pin point exactly what it is. These insoles are not relieving my plantar fasciitis pain but they do give some kind of support or alignment to my arch and eventually I hope it helps with my plantar fasciitis. The only thing I do not like is the length of the insoles are long for my shoes; longer for one of the shoes than the other. Even if I push them to the back of the shoe as much as I can, I feel they kind of wrinkle on the front of the shoe or where the toes are positioned. It is not extremely uncomfortable, but I do feel it and I am getting used to it. I do not want to cut the insoles in order for them to fit in my shoes because I do not want to mess up the shape of the insole. Overall, I think this is a good brand of insoles and will be purchasing another pair. In the pictures I posted, you will be able to see the wrinkled portion of the insole, this is how they fit in my shoes; they fit a little long for my shoes. P.S. My size of shoes is women's 7.5 regular and the size of insoles is for women's 7-8.5
