Quick answerA running belt carries your phone, keys and cards at your waist so your hands and arms stay free. FlipBelt's Zipper belt is a stretchy tube you step into, with three open access points, a zipper pocket and a key hook, sized XXS to XXL and weighing 4.6 oz in medium. SPIbelt's Original is a buckle belt with one expandable 9 x 4 x 2 in pocket for waists of 25 to 38 in. The SPIbelt Dual Pocket PRO adds a second 6.5 x 3 x 2 in pocket on a wider 1.5 in band for waists of 29 to 37 in.

Compare the picks and what to watch out for

Tube belt or buckle belt

Running belts come in two main styles. A tube belt like the FlipBelt is a stretchy loop you step into and wear around your hips; you slide items in through openings around the band. A buckle belt like the SPIbelt is an elastic strap with a zippered pouch that you clip on and tighten.

Tube belts have no buckle to adjust or come undone. Buckle belts adjust to a range of waist sizes, so one size fits more people. FlipBelt says its belt stays in place without bouncing or shifting, and SPIbelt calls its belt bounce-free.

Will my phone fit

FlipBelt says the Zipper belt holds extra-large phones such as the iPhone 12 Pro Max and Samsung Galaxy S21 Ultra, and is wide enough for larger phones in cases and passports. SPIbelt says its 9 x 4 x 2 in pocket holds larger smartphones including the iPhone 13 Pro Max and Samsung Galaxy S20+.

Measure your phone in its case. If it is close to 9 in tall with the case on, the FlipBelt's open tube is more forgiving than a zippered pouch.

Getting the fit right

FlipBelt sells fixed sizes from XXS to XXL, so a belt that is too loose will ride up and one that is too tight will dig in. Check its size chart against your hip or waist measurement where you plan to wear it. SPIbelt adjusts with a buckle and glides: the Original fits 25 to 38 in waists and the Dual Pocket PRO 29 to 37 in.

Wear the belt low on your hips or around your waist and test it on a short run with your full load before a race.

One pocket or two

A single pocket is enough for a phone and a key. If you carry energy gels, a card and keys on long runs, a second pocket keeps them separate so you are not digging past your phone. SPIbelt's Dual Pocket PRO spaces its two pockets close together on a wider 1.5 in band, which it says adds stability.

The FlipBelt Zipper offers a different answer: three open slots around the tube plus one zipper pocket for valuables, and a sewn-in key hook.

Visibility and care

FlipBelt adds a reflective logo for low-light runs, and says the Zipper belt can be machine washed and dried or hung to dry. For running near traffic before sunrise or after dark, pair any belt with a reflective vest.

Which one to buy

Choose the FlipBelt Zipper if you want no buckle, room for a big phone and several items spread around your waist. Choose the SPIbelt Original for the lightest, simplest adjustable belt with one pocket. Choose the Dual Pocket PRO for long runs where you want two separate pockets.

When to talk to a doctor: If you carry medication, an inhaler or a medical device in a running belt, keep it where you can reach it quickly and tell running partners where it is. Stop and loosen the belt if it causes pain, numbness or skin irritation, and seek medical advice for symptoms that persist.
