Reddit mentions of Superfeet EASYFIT Men's Comfort Insoles, Orthotic Shoe Inserts for Flat Dress Shoes, Heel and Arch Support, Mens, Java

Although there are more knowledgeable folks around here, I've had to deal with some plantar fasciitis that flat insoles can flare up so I'll give this a rip. Not sure if you're looking for arch support so YMMV.

• 1)Most welted shoes don't have inserts that can be removed. There may be thin leather liner cemented onto the insole but that's it. The whole shoe is built around the insole like a car is built on the frame.
  
• 2. A resole doesn't change the insole. Maybe google shoe construction and learn for yourself how the welt is sewn onto the insole and upper (Goodyear welted, handwelted, stitchdown, etc) and then the outer sole is attached to the welt. A resole only replaces the outer sole and affiliated stitching. The insole could be replaced I suppose but that would require a complete rebuild on the original last and well... why would you? Might as well buy a new shoe.
     
• 3. Yes some brands have better support than others. In boots I have a pair of Whites which are famous for their Archease insoles. I love them. Nicks does too although I don't have any experience with them. Regarding shoes, Allen Edmunds have never caused me a problem. The best supporting shoe out if the box was actually from Buday a Hungarian maker.
     
• 4. I use Superfeet insoles in some of my flat insole shoes with generous lasts. Vibergs 2030 and Alden Barrie and Trubalance lasts are conducive for the low profile Superfeets. Alden also has their Modified last built to accept orthotics if u get a Prescription. I've never felt the need to see a podiatrist (yet) so These work well in more generous last and these work better in tighter shoes. Many of my shoes just won't accept an insert and I find these work well to avoid the plantar fasciitis.
     
     Good luck. I enjoy all my shoes despite the flat insoles. Good luck

For boots i used these. I was at a specialty shoe store when I first got these. The salesman mentioned that the heel shouldn't spill over the insole like a muffin top and sized mine accordingly. just FYI

For walking sneakers i use these.

I like the brown half soles a lot more than the blues, but the blue one has made unbearable sneakers comfortable enough. I learned that the $35 used GATs that gets posted on here a couple times a year don't do well with my feet. However, once I took the soles out and put the blues in I could actually walk a couple miles in it ok.

If I clap my feet together I have enough space for 1 forefinger to fit. Two fingers width and it'll jam half way. Quite the Donald duck feet lol.

Brannock Size: 11.5 A

Additional notes about feet: Low instep, skinny ankles, Greek toe box, low foot volume

Allen Edmonds 97 Last: 11.5 A is a perfect fit. I also have a pair in 11.5 B and they're a bit loose in terms of overall volume, but definitely wearable.

Nisolo: (they don't give details on lasts) 11 D, with SuperFeet DELUX insoles (size large). The length of the shoes is good, but they are on a relatively high-volume last, so I need the insoles to prevent heel slippage.

No change in width; the inserts just added some height under my heels and arches.

If you want to try Superfeet, and can't find any locally, Amazon has them with free return shipping if they don't fit.

EG still claims their UK sizes are 1/2 lower that US. That applied to me. I am 8.5D, and I took their UK8. I tried on UK7.5 in their shop, and it was too small.

I use these. I am normally a 10.5 C but some lasts and styles dont come in those so if I get a D I have to use theses, just enough to make the shoe fit really well.
