Easily interchanged lenses, amazing field of view, impressive comfort, and fog-free optical technology create a better experience than any other goggle out there.\u003cbr\u003e\u003cbr\u003eAmazon.com\u003cbr\u003e\u003cbr\u003eSMITH OPTICS VAPORATOR SERIES I\/O SNOW GOGGLE\u003cbr\u003e\u003cbr\u003eThe Vaporator Series I\/O snow goggle is built to log serious alpine hours--maintaining comfort and clarity in extreme environments. The I\/O offers easily interchanged lenses and comes with two performance mirror lenses included to match conditions on the hill. The spherical lens combines with Vaporator technology to offer an amazing field of view, impressive comfort, and fog-free optics. The medium-fit goggle is helmet compatible with an easy to adjust silicone backed strap for custom comfort.\u003cbr\u003eMedium Fit\u003cbr\u003ePatented Vaporator Lens Technology with Porex Filter\u003cbr\u003eSpherical, Carbonic-X Lens with TLT Optics\u003cbr\u003eSpherical Lens increases interior volume for fog-free vision\u003cbr\u003e5X Anti-Fog Inner Lens\u003cbr\u003eIncludes Two Performance Mirror Lenses\u003cbr\u003eQuick Release Lens System\u003cbr\u003e3-Layer, DriWix Face Foam\u003cbr\u003eUltra-Wide, Silicone Backed Strap\u003cbr\u003eQuickFit Strap Adjustment System with Clip Buckle\u003cbr\u003eHelmet Compatible\u003cbr\u003eIncludes Microfiber Goggle Bag with Replacement Lens Sleeve\u003cbr\u003eLifetime Warranty\u003cbr\u003e\u003cbr\u003e\u003cbr\u003ePatented Vaporator lens technology utilizes processes previously reserved for aerospace and medical capacities. These lenses are robotically cut and bonded together with an airtight silicone bead to eliminate lens delamination--the number one cause of between-the-lens fogging.\u003cbr\u003e\u003cbr\u003eA micro-porous filter called Porex completes the system. Its composition is structured such that air molecules may pass through the filter while water molecules cannot. By utilizing this filter, the thermal lens is allowed to adjust to varying altitudes while preventing moisture from entering the space between the lenses creating an amazingly strong thermal lens barrier.\u003cbr\u003e\u003cbr\u003eCarbonic-X outer lenses are individually molded to offer optimum scratch and impact resistance, increased visual acuity, and enhanced contrast sensitivity. The inner lens is impregnated with Fog-X lens treatment for increased anti-fog performance. The Carbonic-X lens meets Class 1 optical standards as well as ANSI Z87.1 standards.\u003cbr\u003e\u003cbr\u003eWhen light passes through a medium--such as a lens it refracts, i.e. changes course. If left uncorrected, this refraction can cause visual distortion and eye fatigue. Smith’s TLT straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. What this means for you is that you see with accuracy and increased comfort.\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eMedium Fit and Helmet Compatible\u003c\/li\u003e\n\u003cli\u003eSelect colorways

Patented Vaporator lens technology utilizes processes previously reserved for aerospace and medical capacities. These lenses are robotically cut and bonded together with an airtight silicone bead to eliminate lens delamination--the number one cause of between-the-lens fogging.

A micro-porous filter called Porex completes the system. Its composition is structured such that air molecules may pass through the filter while water molecules cannot. By utilizing this filter, the thermal lens is allowed to adjust to varying altitudes while preventing moisture from entering the space between the lenses creating an amazingly strong thermal lens barrier.

Carbonic-X outer lenses are individually molded to offer optimum scratch and impact resistance, increased visual acuity, and enhanced contrast sensitivity. The inner lens is impregnated with Fog-X lens treatment for increased anti-fog performance. The Carbonic-X lens meets Class 1 optical standards as well as ANSI Z87.1 standards.

When light passes through a medium--such as a lens it refracts, i.e. changes course. If left uncorrected, this refraction can cause visual distortion and eye fatigue. Smith’s TLT straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. What this means for you is that you see with accuracy and increased comfort.

How To Measure Your Shoe Size

Here are the best shoe size conversion charts - in US, UK, European, and inches, for men's, kid's and women's shoes. 
 
If you've ever wondered "What size shoe is a 38?" (It is a men's size 7.5 in the US) or "What is a size 40 in shoes?" (that'd be a US men's size 9.5), read on to learn how to measure shoe sizes in different countries.
 
How do you measure shoe size? It is possible to measure your own foot using a ruler or a Brannock device, but since our feet our three dimensional, this will only approximate your measurements. After you've measured your foot, try using our conversion charts below to see what your size is. Be mindful that different brands, like Altra running shoes vs. Brooks running shoes vs. Oboz hiking boots, maybe run slightly different in sizes.

FAQ & Tips

  • What if I am between shoe sizes? We recommend you should size up, especially in active & sports shoes. This includes running shoes and hiking boots. 
  • Does 0.5 size make a difference in shoes? Yes, it certainly does! Wearing shoes that are too small can cause pain and injuries. Blisters, lose of toenails and bunions can all result from wearing shoes that are even 0.5 size too small. These are common ailments of beginner runners. 
  • Is one foot bigger than the other? It is common for people to have one foot that is slightly bigger than the other. Our tip is that you should buy shoes that fit the larger foot (buy pairs of shoes in the larger size of the two). 
  • Should shoes be tight or lose? Unfortunately, this is not a simple question. Shoes should not be too tight or too lose. You should be able to put a thumbs width at the end of your toe box, between your big toe and the pointy end of the shoe. You should also be able to snuggly fit your index finger between your heel and the back of the shoe. If you have not much (or not enough!) space in either of these areas, try a different size shoe. 
  • When should I try on shoes? A great tip for runners is to try on running shoes at the end of a work day. As you run, just like when you are on your feet for work, your feet swell. You will want to try on running shoes when your feet are at their largest. This allows them to still fit comfortably after a long distance run. 
  • What size shoe should I buy? This shoe chart is not a guarantee your shoes will fit. If you are in the area of Memphis, Tennessee, run on in to one of our running specialty & gear stores and our experienced fit experts will help you out!
