I also believe started doing this to [[Blister Prevention| prevent blisters on ultramarathons]], but over time I found that an open toe box allows my feet to move more naturally . When you run, your toes will tend to splay out at toe off, something that is inhibited by most running shoes. Of course, most people are reluctant to take a knife to their expensive running shoes, so I recommend trying get on an older pair of shoes that are close to the end of their life. This allows you to experiment with relatively little consequence. While cutting open the toe box can dramatically improve your comfort, there are limits to what it can do. If the toe box is too small, then your feet will hang over the edge of the midsole. A common concern with an cutting open the toe boxis getting depraved into your shoe. My experience is that this is only a problem when walking, or running through undergrowth. It's extremely rare for me to get something in my shoes while running. =Instructions=

The most critical part of the cut with a marker that will show up clearly. Mark around is where your toes touch it begins at the sides and/or top of the shoe. Err I've found the best cart starts just ahead of the metatarsal joint. This is just in front of the bulge that forms the ball of your foot on the side inside edge. This ensures that the shoe is in contact with the main part of cutting your foot, and only your toes are free. If you cut too little far back, the shoe will be excessively loose, and likely to rub on the edge of the ball of your foot. If you cut too far forward then your toes will rub as they splay. The other end of the cuts, at the front of the shoe, is far less critical. I simply cut so that I remove the material that would touch my toes, while aiming to leave a bridge that is far enough away from my toes that itwould cause a problem. Some runners don's easy t bother leaving a narrow bridge to the front of the shoe, but I prefer to remove leave it in place as I find it a little more later.]]|[[File:ShoeModCut1.JPG|none|thumb|x300px|Make the initial cuts with a sharp knifecomfortable.]]

|[[File:ShoeModMark.JPG|none|thumb|400px|Mark the line you want to cut with a marker that will show up clearly. Err on the side of cutting too little as it's easy to remove a little more later. With practice you get to know where to cut on the first go, but beginners may need to cut conservatively then go for a short run to see how it feels. Typically just a few minutes will tell you all you need to know. You can then repeatedly cut a little more and try again until you happy.]]|- valign="top"|[[File:ShoeModCut1.JPG|none|thumb|400px|Make the initial cuts with a sharp knife.

This approach doesn't give quite the same level of freedom as completely removing the flap, but it does have some other advantages. You're less likely to get debris in your shoe when walking, as the flap partly covers the opening (it doesn't help much when slogging your way through long grass or undergrowth.) The flap also tends to keep your toes a tiny bit warmer, which is good in winter, but bad in summer. The main benefit is that you're less likely to get rubbing from the edge of the midsole, which can occasionally be an issue.]]
